Predict the reactants for neutralisation reaction where the products are lithium sulphate and water.

Correct option is B

Sol: The correct answer is (b) Sulphuric acid and lithium hydroxide

Key points:

A neutralization reaction involves an acid reacting with a base to form water and a salt. In this case, the given products are lithium sulphate (Li₂SO₄) and water (H₂O).

For the neutralization to produce lithium sulphate and water, the acid must be sulphuric acid (H₂SO₄), and the base must be lithium hydroxide (LiOH).

The balanced neutralization reaction is:

$$H _2​ SO _4​ +2LiOH→Li _2​ SO _4​ +2H _2​ O$$

Information Booster:

• Hydrochloric acid and lithium nitrate
  This would form lithium chloride (LiCl) and water, not lithium sulphate. The reaction would be:

  $$HCl+LiOH→LiCl+H _2​ O$$

  ​​Sulphuric acid and lithium carbonate
  This would produce lithium sulphate (Li₂SO₄), carbon dioxide, and water, not just lithium sulphate and water. The reaction would be:

               $$H _2​ SO _4​ +Li _2​ CO _3​ →Li _2​ SO _4​ +CO _2​ +H _2​ O$$

  Hydrochloric acid and lithium carbonate
  This would produce lithium chloride (LiCl), carbon dioxide, and water, not lithium sulphate. The reaction would be:

  ​$$HCl+Li _2​ CO _3​ →LiCl+CO _2​ +H _2​ O$$​​
