The pH of a liquid can be calculated using the formula pH = -log([H+]), where [H+] represents the concentration of hydrogen ions in the liquid.
The level of acidity in a liquid is commonly measured using the pH scale.
The pH scale ranges from 0 to 14, where a pH value below 7 indicates an acidic solution, a pH value of 7 indicates a neutral solution, and a pH value above 7 indicates a basic solution.
The pH of a liquid can be calculated using the formula pH = -log([H+]), where [H+] represents the concentration of hydrogen ions in the liquid.
For example, if the H+ concentration is 2.31 x 10^-2 moles per liter, the pH would be calculated as pH = -log(2.31 x 10^-2) = 1.64.
So, the correct answer is 1.64.
The probable question may be:
The level of acidity in a liquid is commonly called pH. This level can be calculated with the formula pH = log(1/H^+), where H^+ is the concentration of hydrogen ions in the given liquid. If the H value is 2.31 x 10-moles per liter, the pH is
