Question

Write reactions and if they form a solid for

1) KI reacts with MgCl2

2) KI reacts with Iron (ii) Chloride

3.)Potassium hydroxide with Copper (ii) Chloride

4.)Potassium hydroxide with Calcium Chloride

5.)Potassium hydroxide with Magnesium Chloride

6.)Potassium hydroxide with Iron (ii) Chloride

Answer 1

1) KI reacts with MgCl2

no reaction, all are soluble

2) KI reacts with Iron (ii) Chloride

no reaction; all are soluble

3.)Potassium hydroxide with Copper (ii) Chloride

2KOH(aq) + CuSO4(aq) = Cu(OH)2(s) + K2SO4(aq)

4.)Potassium hydroxide with Calcium Chloride

2KOH(aq) + CaCl2(aq) = Ca(OH)2(s) + 2KCl(aq)

5.)Potassium hydroxide with Magnesium Chloride

2KOH(aq) + MgCl2(aq) = Mg(OH)2(s) + 2KCl(aq)

6.)Potassium hydroxide with Iron (ii) Chloride

2KOH(aq) + FeCl2(aq) = Fe(OH)2(s) + 2KCl(aq)
