Salt Hydrolysis Lab Suggest how various experimental errors would affect your calculated values of Pka, Ka, and or molarity. Clearly explain whether the calculated value would be higher, lower, or no different than the actual value. Possible experimental errors may include: a) The pH buffers used to calibrate the PH meters were 4.5 and 7.5, whereas you thought they were 4.0 and 7.0 and calibrated the pH meters accordingly. b) You decided to take the pH after each addition of...
