Question

Dilute sulphuric acid can be concentrated beyond 98.5%.

• A. True
• B. False

Answer 1

The correct option is B

False

Dilute sulphuric acid cannot be concentrated beyond 98.5% .It is because, at 98.5% concentration, the acid boils at ${338}^0$C as a constant boiling mixture. On boiling above ${338}^0$C, the acid decomposes, giving off water vapour and acid in the same proportion as in the liquid.
