Question

Calculate the pH of the resulting solution if 26.0 mL of 0.260 M HCl(aq) is added to:

(a) 36.0 mL of 0.260 M NaOH(aq)
(b) 16.0 mL of 0.360 M NaOH(aq)

Answer 1

So in your question that ask to calculate the Ph result of the resulting solution if 26 ml of 0.260 M HCI(aq) is added to the following substance. The the result are the following:
A. The result is pH= 14-pOH
B. There are 10ml of 0.26m HCL excees in this reaction so the answer is log(H)+
