Read up on the phenomenon called the common ion effect in your text. You add a small amount of NaOH to a test

tube containing cadmium nitrate solution. Initially nothing happens, but as you add more NaOH you begin to observe the

formation of a white, powdery solid that resembles snowflakes. Eventually, all the precipitate settles to the bottom of your

test tube.

a. Explain why you do not see the precipitate initially as you first begin to add NaOH (aq). In your explanation, discuss

the relationship between Q and Ksp at this point.

b. Explain why you eventually do see a precipitate. In your explanation, discuss the relationship between Q and Ksp at

this point.

c. Which of the following two reagents: HNO

3

or KOH, do you think will increase the solubility of cadmium hydroxide

solution? Explain your answer

± Common-Ion Effect on Solubility for Lead Thiocyanate Lead thiocyanate, Pb(SCN ) 2 Common-Ion Effect Consider the dissolution of AB(s) : AB(s)⇌A+(aq)+ B − (aq) Le Châtelier's principle tells us that an increase in either [ A + ] or [ B − ] will shift this equilibrium to the left, reducing the solubility of AB . In other words, AB is more soluble in pure water than in a solution that already contains A + or B − ions....

1.In gravimetric analysis, it is possible to use the common-ion effect to favor the production of solid precipitate. In this problem you will test this approach to see how effective it is for the gravimetric determination of calcium. Suppose the reaction flask in the gravimetric analysis experiment contains 175 mL of solution before filtering through the Gooch crucible. A precipitate of calcium oxalate monohydrate is collected in the crucible and dried, where: CaC2O4 * H2O <--> Ca2^+ + C2O4^2- +...

The Common Ion Effect: Calculation of pH. When a weak, nitrogen base is protonated, the resulting conjugate acid is given the "ium" suffix to show that it has been protonated and has an overall +1 charge. Thus, the weak base ammonia is protonated to form the ammonium (NH4+) cation. What is the pH of a 0.68 M solution of (CH3)2NH that is also 0.65 M in dimethylammonium sulfate, the salt of it's conjugate acid? The Kb for (CH3)2NH = 5.4...

The common-ion effect and solubility The solubility of a slightly soluble compound can be greatly affected by the addition of a soluble compound with a common ion, that is, with one of the ions in the added soluble compound being identical to one of the ions of the slightly soluble compound. The general result of the addition of the common ion is to greatly reduce the solubility of the slightly soluble compound. In other words, the addition of the common...
