Question

$pH=2$ solution is more acidic than one with $pH6$ by a factor of:

• A. 4000
• B. 2
• C. 10000
• D. 8000

Answer 1

Answer: (C)

10000

$pH=-lo{g}_{10}\left[H^{+}\right]$

For, $pH=2H^{+}={10}^{-2}$

For $pH=6H^{+}={10}^{-6}$

So,$pH=2$ solution is ${10}^4$ times acidic than $pH=6$ solution.
