Answer

General guidance

Concepts and reason

The concept used to solve this problem is determined the product of total ion in the solutions.

Fundamentals

Solubility product constant ():

The equilibrium constant for a low solubility compound (approximately insoluble) is the solubility product constant (). A expression has no denominator because the only species on the left side of the equation is a solid. For example the solubility product constant of AgCl(s) is expressed as follows:

AgCl() Ag+ (aq) + Cl (aq)
Ko=[ Agt la

The solubility product is denoted by , it is the product of the ion concentrations.

The molar solubility is denoted by . . It is the number of moles of solute is dissolved in 1.00 liter of solution.

An equation co-efficient is a number that is placed to the left side of a chemical formula in a balance chemical equation.

Step-by-step

Step 1 of 6

Part A

The balanced chemical reaction for dissolution of calcium carbonate is as follows:

CaCO,(s) → Ca2+ (aq) +CO; (aq)

Dissolution process also known as dissolving process, in which solid salt will dissolve as ions in water. In the process of dissolution; solid going into liquid phase also.

Step 2 of 6

The solubility product constant () for calcium carbonate (Caco) is as follows:

Ko = [Ca2+ ][CO]

The activity (or concentration) of a solid is unity therefore [Caco] =1

Part A

The balanced chemical reaction for dissolution of calcium carbonate isCaCO, → Ca2+ (aq) +CO3- (aq)

The solubility product constant; for calcium carbonate (Caco) isKo = [Ca2+ ][CO]

Solubility product constant ():

The equilibrium constant for a low solubility compound (approximately insoluble) is the solubility product constant (). A expression has no denominator because the only species on the left side of the equation is a solid. For example the solubility product constant of Caco is expressed as follows:

The solubility product is denoted by , it is the product of the ion concentrations.

Step 3 of 6

Part B

The balanced chemical reaction for dissolution of РЬСІ,is as follows:

PbCl2 → Pb2+ (aq) + 2CF (aq)

Dissolution process also known as dissolving process, in which solid salt will dissolve as ions in water. In the process of dissolution; solid going into liquid phase also.

Step 4 of 6

The solubility product constant () for РЬСІ,is as follows:

K. = [Pb2+ ][ Cr

The activity (or concentration) of a solid is unity therefore [РЬСІ,]=1.

Part B

The balanced chemical reaction for dissolution of РЬСІ,isPbCl2 → Pb2+ (aq) + 2CF (aq)

The solubility product constant; for РЬСІ,isK. = [Pb2+ ][ Cr

Solubility product constant ():

The equilibrium constant for a low solubility compound (approximately insoluble) is the solubility product constant (). A expression has no denominator because the only species on the left side of the equation is a solid. For example the solubility product constant of РЬСІ, is expressed as follows:

The solubility product is denoted by , it is the product of the ion concentrations.

Step 5 of 6

Part C

The balanced chemical reaction for dissolution of is as follows:

Agl → Ag* (aq) +
(aq)

Dissolution process also known as dissolving process, in which solid salt will dissolve as ions in water. In the process of dissolution; solid going into liquid phase also.

Step 6 of 6

The solubility product constant; for is as follows:

Kp =[Ag*][T]

The activity (or concentration) of a solid is unity therefore [] =1

Part C

The balanced chemical reaction for dissolution of isAgl → Ag* (aq) +
(aq)

The solubility product constant; for isKp =[Ag*][T]

Solubility product constant ():

The equilibrium constant for a low solubility compound (approximately insoluble) is the solubility product constant (). A expression has no denominator because the only species on the left side of the equation is a solid. For example the solubility product constant of is expressed as follows:

The activity (or concentration) of a solid is unity therefore [AgCl(s)] =1

The solubility product is denoted by , it is the product of the ion concentrations.
