1. The document describes an experiment to test the effect of common ions on the solubility of calcium hydroxide (Ca(OH)2) in water and sodium hydroxide (NaOH) solutions of different concentrations.
2. The results show that the solubility of Ca(OH)2 decreases as the concentration of NaOH increases, due to the common ion effect.
3. The conclusion is that Ca(OH)2 is more soluble in water than in NaOH solutions due to the presence of the OH- common ion in NaOH, which reduces the solubility of Ca(OH)2.

neutralization (or neutralisation, see spelling differences) is a chemical reaction in which an acid and a base react to form a salt. Water is frequently, but not necessarily, produced as well. Neutralizations with Arrhenius acids and bases always produce water where acid–alkali reactions produce water and a metal salt.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
The application of common ion to purify hard water
1. The Application of
Common Ion to Purify
Hard Water
Chemistry- Experiment
Rolla Tyas Amalia
Grade 11 Science
2. Aim: To vanish the hardness of natural water.
Materials:
1. 4 Pippets 11. 2grm Ca(OH)2
2. 8 tube reactions 12. NaOH 0,025 M and 0,1, 50 ml
3. 8 conical flasks 13. 25 ml Hcl, 0,1 M
4. A funnel 14. Distilled water
5. A stative
6. A tube rack
7. Paper Filter
8. A beaker glass 250 ml
9. A gratitude glass
10. A burette
Procedures:
1. Prepare 4 conical flasks, put 2 grm of Ca(OH)2 powder into each flask.
2. Label the flasks with number 1-4.
3. Add 50 ml water into flask 1; 50 ml NaOH 0,025 M into flask 2; 50 ml
NaOH 0,05 M into flask 3; and 50 ml NaOH 0,1 M into flask 4.
4. Plug flask in, then shake and let it for one night.
5. After one night, separate the solutions at each flask so you can get the
filtrate.
6. Put 10 ml of filtrate 1 into conical flask and add 3 drops of methyl
indicator. Titrate the solution with HCL 0,1 M until there is change in
solution color! Make a note on the volume of used HCL.
7. Determine the concentration of OH- in the filtrate using equation V1 M1 =
V2 M2
8. Record the observation in a table.
9. Do a calculation and record the data in the following table:
Saturated Used (OH-) in (OH-) in (Ca2+) in Ksp= (Ca2+)
solution of volume of solution Ca(OH)2 solution (OH-)
Ca(OH)2 HCL 0.1 M
8.7 ml 0.087 M 0.174 M 0.087 M 2.6 x 10^-3
In water
13.2 ml 0.132 M 0.264 M 0.132 M 9.1 x 10^-3
In NaOH 0.025 M
7.3 ml 0.073 M 0.146 M 0.073 M 7.78 x 10^-3
In NaOH 0.05 M
15.3 ml 0.153 M 0.292 M 0.153 M 0.024
In NaOH 0.1 M
3. Evaluating Data
From the data of the experiment, constanta of solubility of Ca(OH)2 in
water is smaller than the constanta of solubility of Ca(OH)2 in NaOH with 0.025
M and 0.05 M. This means that Ca(OH)2 is more soluble in water than in NaOH
with 0.025 M and 0.05 M.
The effect of NaOH solution in the solubility of Ca(OH)2 is reducing the
solubility of insoluble substances, that we known as the common ion effect. We
could see that the solubility of Ca(OH)2 in NaOH is decreasing as the
concentration of NaOH is increasing.
My conclusion is Ca(OH)2 is more soluble in water than NaOH. The NaOH
with bigger concentration will give the common ion effect to the solubility of
Ca(OH)2 in NaOH. The bigger the concentration of NaOH, the smaller the
solubility of the Ca(OH)2, which make the Ca(OH)2 can be more soluble.
Communicating
The effect of common ion to the solubility is reducing the solubility of the
insoluble substance, so that it might be soluble. The effect of common ion to the
value of Ksp is decreasing the value of the Ksp. From the data of the experiment,
the Ksp of Ca(OH)2 in NaOH with 0.1 M is smaller than the Ksp of Ca(OH)2 in
water. This means that salt is more soluble in a solution with common ion than
in water.
