Question

A solution with a pH of 11 has a [H+] of:
11
1 x 10-3
1 x 10-11
1 x 1011
1 x 103

Answer 1

A solution with a pH of 11 has a [H+] of $1.0\times 10^{-11}$

Option B is correct option.

Step-by-step explanation:

A solution with a pH of 11 has a [H+] of= ?

pH=?

Concentration of H+ [H+]= ?

Formula used: $pH=-log[H+]$

Putting values and finding [H+]

$pH=-log[H+]\\\,[H+]\,=10^{-pH}\\\,[H+]\,=10^{-11}\\\,[H+]\,=1.0\times 10^{-11}$

So, A solution with a pH of 11 has a [H+] of $1.0\times 10^{-11}$

Option B is correct option.
