Question

Identify the chemical equation which represents a complete balanced equation for the reaction of

barium chloride with sodium sulphate to produce barium sulphate and sodium chloride.

(a) BaCl2

(aq) + Na2

SO4

(aq)  BaSO4

(s) + NaCl(aq)

(b) BaCl2

(aq) + Na2

SO4

(aq)  2BaSO4

(s) + 2NaCl(aq)

(c) 2BaCl2

(aq) + Na2

SO4

(aq)  2BaSO4

(s) + NaCl(aq)

(d) BaCl2

(aq) + Na2

SO4

(aq)  BaSO4

(s) + 2NaCl(aq)​

Answer 1

Answer:

BaCl2(aq) + Na2SO4(aq) → BaSO4(s)↓ + 2NaCl(aq) is the equation for the reaction. Sodium and chloride ions are the spectator ions.
