Question

consider the following reaction x+Barium chloride gives us y+sodium chloride.
1.identify x and y
2.name the type of reaction

Answer 1

Answer:

• When a reactant X reacts with “Barium chloride” to give a product Y and sodium chloride a double displacement or precipitation reaction takes place.
• In order to form sodium chloride, sodium compound should be a reactant.  

• So the reactant X is sodium sulphate and product Y is barium sulphate.

And the reaction becomes:

$\mathrm{BaCl} 2(\mathrm{aq})+\mathrm{Na} 2 \mathrm{SO} 4 \rightarrow 2 \mathrm{NaCl}(\mathrm{aq})+\mathrm{BaSO} 4(\mathrm{s})$

• Sodium sulphate reacts with barium chloride in a double displacement reaction to form “barium sulphate” (insoluble solid) and sodium chloride.
