1. a)Calculate the pH of a 0.30M formic acid solution (Ka=1.8*10^-4)Weak monoprotic acid. b)Calculate the Ka for a 0.050M solution of HA (weak avid if the pH=4.65 c)What is the pH of the solution which results from mixing 50.0mL of 0.30M HF (aq) and 50.0mL of 0.30M NaOH (aq) at 25C? (Kb of F- =1.4*10^-11) I am having a hard time with these so as much detail as possible would be great, thank you for your time and your help.
