Calculate the pH of a 100.0 mL buffer that is 0.158 M HClO and 0.099 M NaClO after adding 1.0 mL of 5.9 M NaOH solution. (Ka for HClO given at 2.9*10^-8 and assume the volume change of added NaOH solution is negligible)
suppose that a student performing an experiment mistakenly calibrated the pH meter using pH 6 instead of a pH 7 buffer. As a result all pH meter readings were too low.
