Problem- calculate the ph after addition of 40 ml of 0150 m, Ask an Expert

Academics

Problem- Calculate the pH after addition of 40 mL of 0.150 M NaOH to (the original) 40 mL of 0.150 M acetic acid. This is a hydrolysis problem. All the acetic acid has been converted to acetate. The equilibrium will be that of the base, acetate. Get Kb = 10-14/Ka. Solve the weak base equilibrium for hydroxide concentrations. Get pOH. Then use: 14 - pOH = pH.

Explain your computation for completing above problem
