please answer the problem by typing I neeed it very clear

120 points] When a solid is dissociating into its ionic components it is said to be undergoing "dissolution". When the ionic components of the solution are changing to a solid, it is said to be undergoing below 3. "precipitation". Fill in the blanks for the sentences a. lonic impurities washed off the land in flood times and into stream floodwaters Dissolution or Precipitation) is an example of Phosphorus removal from the treated wastewater by the creation of a phosphorus sludge during a chemical reaction is an example of b. 2 c. There are 3 things that solubility depends on that we discussed in class. Name 2 of these things: d. Rank the following species in order of increasing solubility based on their solubility products at 25 C Compound name Solubility Product | Rank (1 soluble) most Aluminum hydroxide Al(OH)3 Calcium Sulfate Calcium Carbonate A3++30H-1x 10-32 2.4 x 10 2 e. What is the [OH-] concentration at equilibrium of Al(OH)s in solution? 2. [3???

Explanation / Answer

a. ionic imputities washed off the land in flood limes and into stream floodwaters is an example of dissolution

b. Phosphorus removal ffrom the treated wastewater by the creation of a phosphorus sludge during a chemical reaction is an example of Precipitation.

c. there are three things that solublity depends on that we discussed in class. Name 2 of these things:

i. temperature

ii. Pressure

d.

Aluminium hydroxide - 3

Calcium Sulphate - 1

Calcium Carbonate - 2

e.

Al(OH)3 -------> Al +3 + 3OH-

Ksp = [Al+3] [OH-]3

        [OH-]= 3 [Al+3]

Ksp =1/3 x [OH-] [OH-]3

1 X 10-32 = 1/3 x [OH-]4

[OH-] = 1.316 x 10-8
