Chemistry

500.0mL of 0.120M NaOH is added to 535mL of 0.250M weak acid(Ka= 5.88*10^-5) What is the pH of the resulting buffer?

No. of moles of NaOH present = molarity bx volume in liters = 0.5L x 0.120= 0.06moles NaOH

No. of moles of acid present = 0.535L x 0.250 = 0.13375 moles

            HX +        NaOH ----> NaX + H2O

           0.13375     0.06        -             -

             -0.06         -0.06      0.06       -

      0.07375            0            0.06         -

Noe, pH = pKa + log[A-]/[HA]

Given, Ka = 5.88E-5 so, pKa = -log[Ka] = 4.23

pH = 4.23 + log(0.06/0.07375) = 4.14
