Equilibrium Question 480
Question: The $ pH $ of a solution is 2. If its $ pH $ is to be raised to 4, then the $ [{H^{+}}] $ of the original solution has to be [MP PET 1994]
Options:
A) Doubled
B) Halved
C) Increased hundred times
D) Decreased hundred times
Show Answer
Answer:
Correct Answer: D
Solution:
If pH of any solution is 2. Then $ [{H^{+}}]={10^{-2}} $ M If pH of any solution is just double then $ pH=4 $ and $ [{H^{+}}] $ will be $ {10^{-4}} $ .
