Which of the following ph levels would be the most acidic? ph 2 ph 5 ph 8 ph 13

pH = 2

Explanation: pH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

Thus as pH and are inversely related, a solution having lower pH will have more amount of concentration. And a solution having more pH will have less amount of concentration.

Acids have pH ranging from 1 to 6.9 , neutral solutions have pH of 7 and bases have pH ranging from 7.1 to 14.

Strong acids which dissociate completely when dissolved in water and have high concentration of will have low pH and vice versa.
