Question

the concentration of H+ionof hel is lx 10-2 moles its PH will be​

Answer 1

Answer:

Solution:

In aqueous solution of is based upon the concentration of ion of and concentration of ion of water.

of

or (due to its neutral behaviour)

So, in aqueous solution of

of HCl of water

Answer 2

Explanation:

On using this relation, pH= –log[H

3

O

+

], we get pH equal to 8. But this is not correct because an acidic solution cannot have pH greater than 7.

It may be noted that in very dilute acidic solution when H

+

concentrations from acid and water are comparable, the concentration of H

+

from water cannot be neglected.

Therefore,

[H

Since HCl is a strong acid and is completely ionized.

[H

The concentration of H
