1. Chemical Reactions and Equations
hard
Write a balanced chemical equation with state symbols for the following reactions.
$(i)$ Solutions of barium chloride and sodium sulphate in water react to give insoluble barium sulphate and the solution of sodium chloride.
$(ii)$ Sodium hydroxide solution (in water) reacts with hydrochloric acid solution (in water) to produce sodium chloride solution and water.
Option A
Option B
Option C
Option D
Solution
$(i)$ $BaC{l_{2\left( {aq} \right)}} + N{a_2}S{O_{4\left( {aq} \right)}}$ $\to $ $BaS{O_{4(s)}} + 2NaC{l_{\left( {aq} \right)}}$
$(ii)$ $NaO{H_{(aq)}} + HC{l_{(aq)}}$ $ \to NaC{l_{(aq)}} + {H_2}{O_{(l)}}$
