The pH value of 0.1 mol dm-3 of acid U is 1. Which statement is true about acid U? A) slightly soluble in water
B) reacts only with a weak alkali
C) the degree of ionization in water is high
D) has a low concentration of hydrogen ions​

the degree of ionization in water is high

Explanation:

The term pH is defined as the negative logarithm of hydrogen ion concentration.

Hence;

pH = -log[H^+]

The pH scale shows the degree of acidity or alkalinity of a solution. A solution of pH 1 is a strong acid. A strong acid dissociates completely in solution.

Hence, acid U has a high degree of ionization in water.
