yes
NaCl will disociate fully into Na + and Cl -
in strong acids like HCl, it will not matter but pH will rise as
pH is determined by the concentration of H+ which will decrease as
NaCl solution will add volume to the reaction mixture. Hence, if
50cc of NaCl and 50cc of HCl mix together, the pH will be affected
as previously, 50 moles of H+ is present assuming HCl solution is
1M/cc over 50/1000 dm3 but now is 50 moles of H+ is present over
100/1000 dm3, (dilution factor = 1/2)
(Hence, pH is not a good acidity indicator, Ka is better - A
levels)
To TS, you are O level student right? If A levels, do consider
common ion effect, :)
