Answer to Problem 49A

The balanced chemical equation of magnesium fluoride is given as

  MgF2(s)Mg+2(aq)+2F-(aq)

This equilibrium is a heterogeneous equilibrium, so the concentration of magnesium fluoride is one. Hence, the solubility product constant for the given reaction is;

  Ksp=[Mg+2][F-]-2

Explanation of Solution

The balanced chemical equation of magnesium fluoride is given as

  MgF2(s)Mg+2(aq)+2F-(aq)

The Solubility expression for the given reaction is given as

  Ksp=[Mg+2][F-]2[MgF2]Ksp[MgF2]=[Mg+2][F-]2

This equilibrium is a heterogeneous equilibrium, so the concentration of magnesium fluoride is one.

  Ksp=[Mg+2][F-]-2

Answer to Problem 49A

The balanced chemical equation of dissociation of calcium phosphate in water is

  Ca3(PO4)2(s)3Ca+2(aq)+2PO4-3(aq)

This equilibrium is a heterogeneous equilibrium, so the concentration of calcium phosphate is one. Hence, the solubility product constant for the given reaction is;

  Ksp=[Ca+2]3[PO4-3]2

Explanation of Solution

The balanced chemical equation of calcium phosphate is given as

  Ca3(PO4)2(s)3Ca+2(aq)+2PO4-3(aq)

The Solubility expression for the given reaction is given as

  Ksp=[Ca+2]3[PO4-3]2[Ca3(PO4)]Ksp[Ca3(PO4)]=[Ca+2]3[PO4-3]2

This equilibrium is a heterogeneous equilibrium, so the concentration of calcium sulphate is one.

  Ksp=[Ca+2]3[PO4-3]2

Answer to Problem 49A

The balanced chemical equation of copper hydroxide is given as

  Cu(OH)2(s)Cu+2(aq)+2OH-1(aq)

This equilibrium is a heterogeneous equilibrium, so the concentration of copper hydroxide is one. Hence, the solubility product constant for the given reaction is;

  Ksp=[Cu+2][OH-1]2

Explanation of Solution

The balanced chemical equation of copper hydroxide is given as

  Cu(OH)2(s)Cu+2(aq)+2OH-1(aq)

The Solubility expression for the given reaction is given as

  Ksp=[Cu+2][OH-1]2[Cu(OH)2]Ksp[Cu(OH)2]=[Cu+2][OH-1]2

This equilibrium is a heterogeneous equilibrium, so the concentration of copper hydroxide is one.

  Ksp=[Cu+2][OH-1]2

Answer to Problem 49A

The balanced chemical equation of dissociation of silver sulphate in water is Ag2SO4(s)2Ag+1(aq)+SO4-2(aq)

This equilibrium is a heterogeneous equilibrium, so the concentration of silver sulphate is one. Hence, the solubility product constant for the given reaction is;

  Ksp=[Ag+1]2[SO4-2]

Explanation of Solution

The balanced chemical equation of silver sulphate is given as

  Ag2SO4(s)2Ag+1(aq)+SO4-2(aq)

The Solubility expression for the given reaction is given as

  Ksp=[Ag+1]2[SO4-2][AgSO4]Ksp[AgSO4]=[Ag+1]2[SO4-2]

This equilibrium is a heterogeneous equilibrium, so the concentration of silver sulphate is one.

  Ksp=[Ag+1]2[SO4-2]
