Write net ionic equations for the reactions that take place when aqueous solutions of the following substances are mixed: a. sodium cyanide and nitric acid, b. ammonium chloride and sodium hydroxide, c. sodium cyanide and ammonium bromide, d. potassium hydrogen sulfate and lithium acetate, e. sodium hypochlorite and ammonia.

A. H₃O⁺ + CN⁻ → H₂O + HCN

B. OH⁻ + NH₄⁺ → NH₃ + H₂O

C. CN⁻ + NH₄⁺ → HCN + NH₃

D. HSO₄⁻ + CH₃COO⁻ → SO₄²⁻ + CH₃COOH

E. ClO⁻ + NH₃ → NO REACTION

Explanation:

Part A.

Sodium cyanide consist of Na⁺ and CN⁻ ions. CN⁻ is a conjugate base and accept H⁺ ion from nitric acid to form HCN (hydrogen cyanide).

Part B.

Ammonium chloride consist of NH₄⁺ and Cl⁻ ions. Sodium hydroxide is a strong base dissociate completely in solution convert into ammonium hydroxide and sodium chloride.

Part C.

Sodium cyanide consist of counter ion Na⁺ . CN⁻ combined with ammonium bromide to form ammonium cyanide and sodium bromide.

Part D.

Potassium hydrohen sulphate consist of potassium counter and hydrogen sulphate ion. Hydrogen sulphate combined with acetate ion to form acetic acid and sulphate ion.

Part E.

There have no reaction because hypochlorite and ammonia both are bases.

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.
