An acidic solution at 25°c will have a hydronium ion concentration and a ph value .

The given question is incomplete. The complete question is:

An acidic solution at 25°C will have a hydronium ion concentration ________ and a pH value ________.

> M, pH < 7.00

< , pH < 7.00

< ,, pH > 7.00

> ,, pH > 7.00

> M, pH < 7.00

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.

As pH of acids is less than 7, the hydronium ion concentration is greater than

Thus the correct option is > M, pH < 7.00

dynamic equilibrium is the answer.
