Q71
Two solutions A1 and A2 have pH value of 2 and 6 respectively. It implies that the solution
A.
A1 is more alkaline than solution A2
B.
A1 is highly acidic
AnswerC.
A1 is very slightly acidic
D.
Both A & C
Answer: Option B
Solution
Answer: Option B
Solution:
The pH scale measures the acidity or alkalinity of a solution, ranging from 0 (most acidic) to 14 (most alkaline), with 7 being neutral.A solution with pH 2 (A₁) is strongly acidic, since it is much lower than 7.
A solution with pH 6 (A₂) is slightly acidic, as it is just below neutral.
Therefore, A₁ is highly acidic compared to A₂.
Option A is incorrect because A₁ is not alkaline at all, and Option C is incorrect because pH 2 indicates strong acidity, not slight acidity.
Hence, the correct interpretation is that A₁ is highly acidic.
