Question

The correct experiment set-up to study the reaction between barium chloride and sodium sulfate is

• A. I
• B. II
• C. Both I and II
• D. Neither I nor II

Answer 1

The correct option is B

II

The explanation for the correct option:

Option B: Figure II:

1. When the solution of Barium chloride reacts with the solution of Sodium sulfate, a white precipitate of Barium Sulfate and Sodium chloride is formed.
2. The chemical reaction:

${\mathrm{BaCl}}_2\left(aq\right)+{\mathrm{Na}}_2{\mathrm{SO}}_4\left(aq\right)\to {\mathrm{BaSO}}_4\downarrow +2\mathrm{NaCl}\left(aq\right)$

3. It is the correct experiment setup to study the reaction between Barium chloride and Sodium sulfate.

Explanation of the incorrect option:

Figure I:

When the powder of Barium chloride reacts with the powder of Sodium sulfate, we will not get any products as both are in a solid phase.

Hence, Option B is correct., Figure II.
