Remaining volume of solution = 400 ml
Mass of HNO3 = 25.2 – 11.5 = 13.7
Molarity = = 0.54 M = 54 * 10-2 M

Phenolphtalein is a pH dependant indicator. It is a weak acid which is colourless in acidic medium but gives pink colour in basic medium. The pink colour is due to its conjugate form. Phenolphthalein dissociates in basic medium. Therefore, assertion is true but reason is false.

0.001 M NaOH solution has [OH-] = 0.001 M = 10-3 M
Using ; pOH =
=
pOH = 3
pH = 14 – pOH
pH = 14 – 3
pH = 11
