As solids do not exert pressure, so their partial pressure is taken as unity.
MCQ (Single Correct Answer)
Which statement is wrong about pH and H+?
pH of neutral water is not zero.
Adding 1 N solution of CH3COOH and 1 N solution of NaOH, pH will be seven.
[H+] of dilute and hot H2SO4 is more than concentrated and cold H2SO4
Mixing solution of CH3COOH and HCl. pH will be less than 7.
CH3COOH is weak acid while NaOH is
strong base, so one equivalent of NaOH can
not be neutralized with one equivalent of
CH3COOH. Hence the solution of one equivalent
of each does not have pH value as 7. Its pH will be
towards basic side as NaOH is a strong base
hence conc. of OH– will be more than the conc.
