Question
Chapter 15, Problem 15.40CP
Interpretation Introduction
Interpretation:
The given representations of solutions should be classified as unsaturated, saturated, or supersaturated solutions.
Concept introduction:
Saturated:
A solute is dissolved in solvent to give a solution. In this process, formation of precipitate results the unable to dissolving of solute into the solution, this solution is known as saturated solution.
Unsaturated:
Lesser the amount of solute that dissolved into the solution than saturated solution gives an unsaturated solution.
Supersaturated:
Higher the amount of solute that dissolved into the solution than saturated solution by increasing temperature gives a supersaturated solution.

A basic solution contains the iodide and phosphate ions that are to be separated via selective precipitation.The I– concentration, which is 9.20×10-5 M, is 10,000 times less than that of the PO43– ion at 0.920 M .A solution containing the silver(I) ion is slowly added. Answer the questions below.Ksp of AgI is 8.30×10-17 and of Ag3PO4, 8.90×10-17.
Calculate the minimum Ag+ concentration required to cause precipitation of AgI. mol/l
Calculate the minimum Ag+ concentration required to cause precipitation of Ag3PO4. mol/l
B represents an acid-base indicator and behaves like a base. Its dissociation equilibrium in an aqueous solution can be written as:
B(ac) + H2O(l) <-> +BH(ac) + OH(ac)
If B (ac) is yellow +BH is red. Using Le Châtelier's principle, predict the color of the indicator by adding a few drops of the indicator to an aqueous solution of HCl and an aqueous solution of NaOH. Write the corresponding chemical reactions.
Phenolphthalein is another pH indicator. In solution, it's colorless, but its ion is fuchsia. Ionization changes the compound's color. It is colorless between pH of 1 and 8.2, fuchsia between 8.3 and 10, and colorless above 10. At pH less than 1, the color turns orange-red, as in sulfuric acid. However, not all strong acids will exhibit this color. What are the chemical equations that show the color change of dropping Phenolphthalein to NaOH, KOH, and a very acidic solution from:
NaOH and KOH
Colorless to Fuchsia
Fuchsia to Colorless
Very acidic solution
Colorless to red-orange
