Question

What is the ph of a 0.014 M HCL solution?

Answer 1

pH
`= 1.853`

Step-by-step explanation:

For every mole of hydrochloric acid, one mole of hydronium ion is required. Thus, in order to neutralize 0.014 moles of HCL, 0.014 moles of hydronium is required.

`[H_3O^+] = [HCl] = 0.014`

pH
`= -log [H^+] = -log [H_3O^+]`

Substituting the available values in above equation, we can say that the pH of the solution is equal to

`- log (0.014)`

pH
`= 1.853`

pH of a
`0.014` M HCL solution
`= 1.853`
