Answer:

75 ml of 0.1M  base neutralizes 25 ml of 0.1M acid, which means the acid has 0.3 moles/L of H ion

but that means each molecule of the acid has 3 times as many H ions aH ions in a molecule of NaOH

which means the formula for the acid must be H3A and

the value of x in

HxA is 3

Explanation:

75ml of a solutipn of 0.1moL  l-1 NaOH neutralises 25ml of a solution of an acid. The formula of the acid is HxA and the concentration of the acid is 0.1mol l-1. What is the value of x?​

the concentration of both the and the base are the same at 0.1M

the base...NaOH has 0.1 moles/L of OH ion

75 ml of 0.1M  base neutralizes 25 ml of 0.1M acid, which means the acid has 0.3 moles/L of H ion

but that means each molecule of the acid has 3 times as many H ions aH ions in a molecule of NaOH

which means the formula for the acid must be H3A and the value of x in

HxA is 3
