Answer: the solution is acidic and with a pH value of 2.7

Step-by-step explanation:

The pH of a solution is the concentration of hydrogen ion concentration in the solution. Mathematically, it is expressed as pH = -log(H+), where H+ is the concentration of hydrogen ion

So, for when [H+] = 0.0023 M

pH = -log(0.0023 M)

pH = -(-2.638)

pH = 2.638 (The minus signs cancelled out)

Round the pH value to the nearest tenth as 2.7.

On the pH scale, readings are from 1 to 14, and pH values less than 7 are regarded as acidic while pH values above 7.0 are basic.

Thus, the solution is acidic and with a pH value of 2.7
