Question

Ph=3.31 then find out H+

Answer 1

pH= -log[H+], So, [H+]= 10^-pH= 10^- 3.31

Answer 2

Answer: the concentration of $[H^+]$ is 0.0004 M.

Solution:

pH of the solution is defined as negative logarithm of concentration of hydronium ion concentration.

Given: $pH=3.31,[H^+]=?$

$pH=-log[H^+]$

$3.31=-log[H^+]$

$[H^+]=antilog[-3.31]=0.0004 M$
