Question

43. (a) What happens when an aqueous solution of sodium sulphate reacts with an aqueous solution of barium
chloride ?
(6) Write the balanced chemical equation for the reaction which takes place.
(C) State the physical conditions of reactants in which the reaction will not take place.
(d) Name the type of chemical reaction which occurs.
(e) Give one example of another reaction which is of the same type as the above reaction.​

Answer 1

Answer:

a) A heavy white precipitate of barium sulphate is formed

b) Na2SO4 (aq.) + BaCl2 (aq.) → BaSO4↓(ppt.) + 2NaCl (aq.)

c) When both the reactants are in solid state

d) Precipitation reaction

e) 2AgNO3 (aq.) + CaCl2 (aq.) → 2AgCl↓(ppt.) + Ca(NO3)2 (aq.)
