Question

The pH of a liquid is a measure of how acidic or basic it is. The concentration of hydrogen ions in a liquid is labeled [H+]. Use the formula pH = –log[H+] to find the pH level, to the nearest tenth, of a liquid with [H+] about 5.4 x 10–14.
A. 14.7B. 13.3C. 14.0D. -14.7

Answer 1

Answer:

option (b)

Step-by-step explanation:

Concentration of [H+} = 5.4 x 10^-14

According to the formula

pH = - log [H+]

$pH = - log[5.4\times 10^{-14}]$

$pH = - log[5.4] -log [10^{-14}]$

pH = 14 - log 5.4

pH = 14 - 0.732

pH = 13.3

Thus, the pH is 13.3
