Answer:
a) P
b)Q; R
Explanation:
a) Blue litmus paper turns red under acid... and the pH of acid is less that 7... so, here P is only acidic in nature... so, it will turn blue litmus paper to red...
b) in an alkaline (base) fluid the methyl orange doesn't change its colour... and the pH of alkaline is more that 7... so, here Q and R is a base. So, it will not change its colour...
