Question

While performing an activity in the lab, four students added sodium sulphate solution to four different solutions taken in four different test tubes. In which test tube is a white precipitate observed after the reaction ?​

Answer 1

Answer:

When a solution of sodium sulphate is added to a solution of barium chloride, then a white precipitate of barium sulphate is formed along with sodium chloride solution. Hence, this reaction is precipitation reaction.

Explanation:

When a solution of sodium sulphate is added to a solution of barium chloride, then a white precipitate of barium sulphate is formed along with sodium chloride solution. Hence, this reaction is precipitation reaction

Answer 2

When a solution of sodium sulphate is added to a solution of barium chloride, then a white precipitate of barium sulphate is formed along with sodium chloride solution. Hence, this reaction is precipitation reaction.

Explanation:

• When a solution of sodium sulphate is added to a solution of barium chloride, a white precipitate of barium sulphate will be formed immediately.
• This type of reaction is called precipitation reaction as the $Baso4$precipitate thus formed is of white color.
• Sodium sulphate chemically reacts with barium chloride in the form of their aqueous solution to form a white precipitate of barium sulphate.
