Question

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

Answer 1

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 ________.

$[H_3O^+]$ > $1\times 10^{-7}$ M, pH < 7.00

$[H_3O^+]$ < $1\times 10^{-7}$, pH < 7.00

$[H_3O^+]$ < $1\times 10^{-7}$,, pH > 7.00

$[H_3O^+]$ > $1\times 10^{-7}$,, pH > 7.00

Answer: $[H_3O^+]$ > $1\times 10^{-7}$ 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.

$pH=-\log [H_3O^+]$

$7=-log[H_3O^+]$

$[H_3O^+]=10^{-7}$

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

Thus the correct option is $[H_3O^+]$ > $1\times 10^{-7}$ M, pH < 7.00
