Question

An excess of dilute sulphuric acid reacts with both aqueous barium hydroxide and aqueous barium chloride respectively. In what way are the two reactions the same? *

A gas is evolved

An insoluble salt is formed

Their final pH is 7

A base is produced

​

Answer 1

Answer:

Correct Option Is C

Their Final pH Is 7

Answer 2

Both processes are similar as an insoluble salt is formed. (option 2)

The reaction of dilute sulfuric acid with barium hydroxide

• Barium hydroxide is a strong base, whereas dilute sulfuric acid is moderately strong.

• They undergo a neutralization reaction to form salt and water.

• The equation is:

                            H₂SO₄ + Ba(OH)₂   →    BaSO₄ + 2H₂O

                                                                barium sulfate

Barium sulfate precipitates as a white solid.

The reaction of Sulfuric Acid and Barium Chloride

• As in the case of barium hydroxide and sulfuric acid, a displacement reaction occurs.

• The equation is:

                        H₂SO₄ + BaCl₂   →   BaSO₄ + 2HCl

Here also, barium sulfate precipitates out as a white solid.

Thus, the correct option is 2. An insoluble salt is formed.
