Question

[H+] for a solution is2.65 x 10-2 M.This solution is

Answer 1

Answer

A. Acidic

Explanation

Given:

[H⁺] = 2.65 x 10⁻² M

Note that: the pH values range from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

Also, the pH of a solution can be determine using the pH formula below:

$pH=-\log \lbrack H^+\rbrack$

So pH = - log [2.65 x 10⁻²]

pH = 1.58

The pH of the solution fall in the acidic range. Hence, the solution acidic.
