This document outlines a student project on studying the effect of metal coupling on rusting of iron. It includes an introduction explaining rusting and corrosion of metals. The aim is to study how coupling iron with other metals affects its rusting. The experiment involves cleaning iron nails and coupling them with zinc, copper, or magnesium strips before placing in agar solution. Observations will note which nails rust and the color of patches formed, helping determine if more electropositive or less electropositive metal couplings increase or decrease iron rusting. The conclusion is that coupling iron with more electropositive metals like zinc and magnesium resists corrosion, while coupling with less electropositive copper increases rusting.

investigation project of chemistry on metal coupling
This document summarizes a student's investigatory project on the effect of metal coupling on rusting of iron. The student coupled iron nails with zinc, magnesium, copper, and no metal as a control. They observed that coupling iron with the more electropositive metals zinc and magnesium prevented rusting, as seen by the formation of blue patches around the nails. Coupling iron with the less electropositive copper facilitated rusting, as seen by the formation of pink patches. The student concluded that coupling iron with more electropositive metals resists corrosion and rusting, while coupling with less electropositive metals increases rusting.

This document describes a study on the synthesis and characterization of pure, nickel-doped, and iron-doped tin oxide nanoparticles. The nanoparticles were synthesized via a co-precipitation method and analyzed using various techniques. X-ray diffraction analysis showed that the nanoparticles crystallized in the tetragonal rutile structure. UV-visible spectroscopy revealed that doping reduced the optical band gap. Fourier transform infrared spectroscopy confirmed the incorporation of nickel and iron into the tin lattice. Photoluminescence spectra exhibited blue emission peaks attributed to electron transitions involving defect levels. Scanning electron microscopy images displayed nanoparticle morphology and energy-dispersive X-ray spectroscopy confirmed the presence of tin, oxygen, and dopants in the samples.

This document describes an experiment to study the effect of metal coupling on rusting of iron. Iron nails were coupled with zinc, magnesium, or copper and placed in agar solution. Iron coupled with zinc or magnesium did not rust, as indicated by a pink color change, because these more electropositive metals prevent corrosion of iron. However, iron coupled with less electropositive copper did rust, as shown by a blue color change, because copper does not protect iron from corrosion. The experiment demonstrates that coupling iron with more electropositive metals inhibits rusting, while coupling with less electropositive metals allows rusting.

RO-P2O5-ZnO-Pb3O4 (R=Li, Na and K) glasses containing 0.1concentrations of MnO have been prepared. The structural, optical and physical properties of prepared glasses are studied by XRD, UV-Visible, EPR and FTIR techniques. The nature of local symmetry and structural information of the neighboring atoms of dopant ions (Mn2+) in the host matrix have been understood by evaluating the crystal field strength (Dq) and Racah (B & C) parameters. The combined analysis of optical absorption and EPR spectroscopy has indicated that the manganese ions exist in Mn2+ (in octahedral) local coordination sites. FTIR results showed that PO4 are the main structural unit of the glass system and the manganese ions are located in the glass matrix network.

Soot particulates in engine exhausts pose a severe threat to the environment and human health – causing cancer, affecting the heart and lungs and drives metal processes. This study proposes a practical,
real-world application of transition metal modified natural clay as an environmentally benign, low-cost,
green catalyst for soot oxidation. Ni and Co (NC-Clay) incorporated natural clay catalysts were prepared
by a simple wet impregnation method and meticulously characterized by different characterization
techniques. The catalyst exhibited higher H2 absorption at a lower temperature with similar trends as
observed in O2 TPD that indicated a remarkable redox property, which is useful for applications as a
catalyst in soot oxidation. Excellent catalytic activity with a very low T50 of 358 1C was observed and can
be accredited to the improved surface oxygen vacancies and thermal stability by the metal modification
of clay

Cubic structured nickel-zinc ferrite nanoparticles (Ni0.5Zn0.5Fe2O4) have been synthesized by thermal treatment method. This simple procedure employed an aqueous solution containing only metal nitrates as precursors, polyvinyl pyrrolidone as a capping agent, and deionized water as a solvent. The solution was thoroughly stirred for 2 hour, dried at 353 K for 3 hour, the dried material crushed into powder and calcined the powder at 873 K to remove organic substances and crystallize the particles. The microstructure properties of the prepared ferrite nanoparticles were measured using FTIR, XRD, TEM, and EDX and the magnetic properties were determined using VSM and EPR. The average particle size increased from 7 to 22 nm with the increase of calcination temperature from 723 to 873 K. The saturation magnetization, coercivity field, and g-factor increased respectively from 24 emu/g, 11 G, and 2.0673at 723 K to 38 emu/g, 60 G, and 2.1227 at 873 K. This method offers simplicity, a low cost, and an environmentally friendly operation since it produces no by-product effluents.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

- 3. Certificate This is certify that Prasant of class twelfth a has successfully completed the investigatory project on the topic of to study the effect of metal coupling on rusting of iron under the influence of Dr Man singh Meena(pgt chemistry) during the year 2021-22 as per the prescribed syllabus of cbse. Sing of internal examiner Sign of principal
- 4. ACKNOWLEDGEMENT I would like to express my special thanks of gratitude to my teacher Dr M.S Meena as well as our principal who gave me the golden opportunity to do this wonderful project on the topic which also help me in doing a lot of research and I came to know about so many new things I am really thankful to them.
- 5. Introduction Metals and alloys undergo rusting and corrosion. The process by which some metals when exposed to atmospheric condition i.e., moist air, carbon dioxide form undesirable compounds on the surface is known as corrosion, The compounds formed are usually oxides . Rusting is also a type of corrosion but the term is restricted to iron or products made from it .Iron is easily prone to rusting making its surface rough. Chemically, rust is a hydrated ferric oxide.
- 6. Practical 1 Aim: to study the effect of metal coupling on rusting of iron.
- 7. Requirements for experiment: 1)TWO PETRI DISHES 2) FOUR TEST – TUBE 3) FOUR IRON NAILS 4) BEAKER 5) SAND PAPER 6)WIRE GAUGE 7) GELATIN 8) COPPER, ZINC & MAGNESIUM STRIPS 9)POTASSIUM FERRICYANIDE SOLUTION 10)PHENOLPHTHALEIN.
- 8. Procedure 1)At first we have to clean the surface of iron nails with the help of sand paper. 2) After that we have to wind zinc strip around one nail, a clean copper wire around the second & clean magnesium strip around the third nail. Then to put all these three and a fourth nail in Petri dishes so that they are not in contact with each other. 3) Then to fill the Petri dishes with hot agar agar solution in such a way that only lower half of the nails are covered with the liquids .Covered Petri dishes for one day or so. 4) The liquids set to a gel on cooling. Two types of patches are observed around the rusted nail, one is blue and the other pink. Blue patch is due to the formation of potassium ferro- ferricyanide where pink patch is due to the formation of hydroxyl ions which turns colourless phenolphthalein to pink.
- 9. Observation S.No. Metal Pair Colour of the patch Nails rusts or not 1 Iron- Zinc 2 Iron - Magnesium 3 Iron- Copper 4 Iron - Nail
- 10. Conclusion: It is clear from the observation that coupling of iron with more electropositive metals such as zinc and magnesium resists corrosion and rusting of iron. Coupling of iron with less electropositive metals such as copper increases rusting.
- 11. Bibliography Bibliography: For our project we have taken help from following sources ; 1) Comprehensive (Practical Chemistry – XII) 2) Internet- www.wikipedia.com, www.encylopedia.com 3) NCERT Chemistry Textbooks.
