Solution

The correct option is A Is strongly acidic than boric acid but weakly acidic than $K H F_{2}$
When boric acid is reacted with KHF2 (KF,HF), KBF4 salt is produced.
2KHF2 + H3BO3 → KBF4 + KOH + 2H2O
Potassium

solution will have to be added?

A solution of 10% boric acid is to be diluted by adding a 4% boric acid solution to it. The resulting mixture is to be more than 5% but less than 8% boric acid. If we have 750 litres of the 10% solution, then the quantity of the 4% solution that has to be added will lie between
