If [H+] = 10–x, then pH of the solution will be-

A

x

B

10x

C

5x

D

x/10

Answer

x

Explanation

Solution

The pH of a solution is defined as the negative logarithm (base 10) of the hydrogen ion concentration [H+][H^+]. The formula is: pH=−log⁡10[H+]pH = -\log_{10}[H^+] Given that the hydrogen ion concentration is [H+]=10−x[H^+] = 10^{-x}. Substituting this value into the pH formula: pH=−log⁡10(10−x)pH = -\log_{10}(10^{-x}) Using the logarithm property log⁡b(by)=y\log_b(b^y) = y, we can simplify the expression: pH=−(−x)pH = -(-x) pH=xpH = x Therefore, the pH of the solution is xx.
