How Do You Find the PH Level of Solution?

To find the pH of a solution, calculate the concentration of hydronium ions present in the solution. Water dissociates into a hydronium ion and hydrogen oxide. The pH level can be calculated using the expression pH= -log (H3O).

For instance, the pH of a solution with a 0.0025M hydronium ion concentration is calculated as pH= -log (0.0025) which is equal to 2.60. This means the solution is highly acidic. As a rule, acids have higher concentration levels of hydronium ion than hydroxide ions while bases have higher levels of hydroxide ions compared to hydronium ions

The pH level of a solution refers to the measure of acidity or alkalinity in a solution and can be ranked using a pH scale. The pH scale ranges from 1 to 14. Solutions with a pH level below 7 are considered acidic while those above 7 are considered to be a base. The level of acidity increases by a factor of 10 as the pH scale progresses. So a liquid with a pH level of 3 is 10 times more acidic than another with a pH level of 4 and a 100 times more acidic than another with a pH level of 5. The same is true for alkalines. Acids and alkalines of similar pH levels can neutralize each other to form water and salt. Water, however, has a pH level of 7, which is considered neutral.
