Chemistry-PH Calculation

[Sepehr]

Hi,

What is the PH of the solution resulting from the mixture of 15mL of H2SO4 0.12 mol/L with 17  mL of NaOH 0.25 mol/L? What Will be the new PH after addition of 5mL of NaOH 0.25 mol/L?

Could someone help me do this exercice? Or just give me the formula?

Thank you.

Please show your attempt.  If you can, please explain where you got stuck.

First, do you understand how "pH" is defined?  Everything depends on definitions!

I'd say it starts with writing down and understanding the reaction equations, noting that H₂sO₄ is a diacid.

Have you done this at least ?
