1.Assuming not volume change, calculate the pH of a solution made from 0.0500mols of NaOH added to 1.50L of a buffer containing 0.100mol of a weak acid and 0.100mol of its conjugate base. The pKa of the weak base is 5.00.
Homework Answers
Correct your question with pka of weak acid instead of
weak base because here we are dealing with weak acid . Ok
