A student prepared a buffer solution containing both 0220 M sodium acetate (NaC_2H_3O_2) and 0.150 M acetic acid (HC_2H_3O_2, K_3 = 1.8 x 10^-5. What is the pH of the solution? If 0.010 moles of HCI were added to 100 ml of the buffer solution prepared above, what would the new pH the solution be? Household bleach is a solution of sodium hypochlorite, NaOCl, If the K_a for is 3.0 x 10^-4, what is the pH of an 0.100 M solution of NaOCl?
