Question

a beer has ph of 4.30.what is [H3O+]

Answer 1

The $[H_3O^+]$ is $5.01\times 10^{-5}M$

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.

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

Putting in the values:

$4.30=-\log[H_3O^+]$

$[H_3O^+]=antilog(-4.30)$

$[H_3O^+]=5.01\times 10^{-5}M$
