For each of the following reactions predict the products, converting each to a balanced formula equation. Include physical states in your answer.

a.(a) Aqueous solutions of copper(II) sulfate and potassium hydroxide are mixed together. (The solution turns cloudy and light blue during the reaction.)

(b) Aqueous solutions of phosphoric acid and sodium hydroxide are mixed together. (Heat is produced during the reaction.)

(c) Solid sodium bicarbonate is mixed with phosphoric acid. (Bubbles of gas are formed during the reaction.)

(d) Aqueous solutions of aluminum chloride and lead(II) nitrate are mixed together. (The solution turns cloudy white during the reaction.)

Expert Solution

(a) Aqueous solutions of copper(II) sulfate and potassium hydroxide are mixed together.
(The solution turns cloudy and light blue during the reaction.)

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

(b) Aqueous solutions of phosphoric acid and sodium hydroxide are mixed together.
(Heat is produced during the reaction.)

H₃PO₄(aq)+3NaOH(aq)--> Na₃PO₄(aq)+ 3H₂O(l)

(c) Solid sodium bicarbonate is mixed with phosphoric acid.
(Bubbles of gas are formed during the reaction.)

2 NaHCO₃(s) + H₃PO₄(aq) → Na₂HPO₄(aq) + 2 H₂O(l) + 2 CO₂(g)

(d) Aqueous solutions of aluminum chloride and lead(II) nitrate are mixed together.
(The solution turns cloudy white during the reaction.)

2AlCl₃(aq) + 3Pb(NO₃)₂(aq) ===> 3PbCl₂(s) + 2Al(NO₃)₃(aq)
