Answer:

C = 1

Explanation:

For a strong acid, equation of dissociation reaction;

HX(aq) + H2O(l) —> X- + H3O+

For a strong acid, the equilibrium reaction lies strongly to the right.

pH = -log10[H3O+] = -log10[0.1] = -(-1) = 1.

Answer : Option C) 1

Explanation : Using the formula for finding pH of strong acid,

pH = - log_{10} [H^{+}] = -log_{10} [0.1]
= -log_{10} 10^{-1} = - (-1) = 1.

This calculation shows how to find the pH of any acid if the concentration is given.
