The Boiling point of the benzene would be
bp= 80.1C
kb=2.53
The boiling point of the carbon tetrachrloride would be
bp=80.1
kb=50.3
Answer:
(iii) A has pH greater than 7 and B has pH less than 7
Explanation:
Phenolphthalein is a common indicator in acid base titrations. It turns pink in basic conditions and turns colorless in acidic conditions. Thus on addition of solution A it becomes pink so A should be basic having pH more than 7. On addition of B , it turn out to be colorless means that B is an acidic solution having pH less than 7.

Protons are positive
Neutrons are neutral
Electrons are negatively charged
