Question

Which of the following is not a strong acid?(a) HCl (b) HBr (c) HI (d) HF

Answer 1

Answer:

HF is not a strong acid due to strong hydrogen bonding through which it doesn't give H+ ions quickly in the solution.

Answer 2

In a diluted aqueous solution, hydrogen fluoride is a weak acid.

Explanation:

HF is not a strong acid because hydrogen bonding is high and it does not donate as many of its H+ ions as the other acids.

It is used in the manufacture of compounds like Prozac, Fluorine and Teflon. Hydrogen fluoride solution is acidic, colourless and highly corrosive. It is commonly used to etch silicon wafers and glass.

Hydrofluoric acid can cause deep burns when it comes into contact with skin.
