Answer 1

Answer: pH of an
`H_2SO_4` solution is 4.34

Step-by-step 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.

`pH=-\log [H^+]`

`H_2SO_4\rightarrow 2H^++SO_4^(2-)`

Putting in the values:

`pH=-\log[4.58* 10^(-5)]`

`pH=4.34`

Thus pH of an
`H_2SO_4` solution if the
`[H^+]` is
`4.58* 10^(-5)]` is 4.34
