Class 7 chapter 5 Acids ,bases and salts ppt 1
This document discusses acids, bases, and indicators. It provides examples of natural acids and bases commonly used in daily life. It explains that indicators are substances used to determine if a substance is acidic or basic by changing color when added. Examples of natural indicators discussed include litmus, turmeric, and china rose. Litmus extracted from lichens changes color from mauve to red in acids and blue in bases. Turmeric and soaked china rose petals also change color when added to acids versus bases.
Acid and bases and salts
There are two main types of acids: organic acids which are obtained from plants and animals, and mineral acids which are derived from inorganic materials. Acids and bases can be classified as strong or weak based on their corrosive properties and reaction behavior. A neutralization reaction occurs when an acid and base react to form a salt and water, resulting in a neutral solution. Neutralization reactions have many applications, including treating ant stings, indigestion, soil acidity, sewage waste, and protecting teeth. Indicators like litmus paper and natural dyes can be used to determine whether a solution is acidic, basic, or neutral.

Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.

SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4
Signatures of wave erosion in Titan’s coasts
The shorelines of Titan’s hydrocarbon seas trace flooded erosional landforms such as river valleys; however, it isunclear whether coastal erosion has subsequently altered these shorelines. Spacecraft observations and theo-retical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion,but the observational evidence of waves is indirect, and the processes affecting shoreline evolution on Titanremain unknown. No widely accepted framework exists for using shoreline morphology to quantitatively dis-cern coastal erosion mechanisms, even on Earth, where the dominant mechanisms are known. We combinelandscape evolution models with measurements of shoreline shape on Earth to characterize how differentcoastal erosion mechanisms affect shoreline morphology. Applying this framework to Titan, we find that theshorelines of Titan’s seas are most consistent with flooded landscapes that subsequently have been eroded bywaves, rather than a uniform erosional process or no coastal erosion, particularly if wave growth saturates atfetch lengths of tens of kilometers.

- 5. EXAMPLE-
- 6. Miniral acid- The acids which are prepared from the mineral of the earth.miniral acids are man-made acids. Miniral acids are also known as Laboratory acids.
- 7. EXAMPLE-
- 8. BASES Base is a substance which reacts with acid to form salt and water. Bases are bitter in taste. Base is also known as Alkali.
- 9. EXAMPLE
- 10. INDICATORS An Indicator is a type of 'dye’ which tells whether the substance is acidic or basic by change in its colour. Indicators are of two types: Natural indicators and Synthetic indicators.
- 11. Natural Indicators: Naturally occurring Indicators are known as Natural indicators. Now we will study about some of the important natural indicators.
- 12. LITMUS Litmus solution is a purple coloured 'dye’ which is extracted from 'lichen’ plant. Litmus is made into two types- blue litmus and red litmus. We use litmus inthe form of strips of litmus paper.
- 13. Acid turns blue litmus to red. Bases turns red litmus to blue.
- 14. China rose Indicator China rose Indicator is a light pink colored solution which is extracted from the red flower of china rose (hibiscus).
- 15. Soak some petals of china rose in warm water for a couple of hours. The red- coloured solution is used as an indicator for detecting an acid or a base solution. It turns into magenta in acidic medium and green in basic medium.
- 16. Turmeric indicator Turmeric contains yellow dye.turmuric turns red in basic solution and turmeric doesn’t Show any changes when it is added to acidic solution.
- 17. SYNTHETIC INDICATORS Synthetic Indicators are man made indicators. There are two types of synthetic indicators- Phenolphthalein indicator- phenolphthalein indicator is colourless in acidic solution and it gives pink colour in basic solution.
- 18. Menthyl Orange-Methyl orange shows red color in acidic medium and yellow color in basic medium
- 19. SALT When acid and base reacts with base then they form salt and water and this process is known as Neutrilsation.
