Which one of the following is correct option: hydrogen,
hydroxide, peroxide?
pH is a measure of the
ion concentration of a
solution.

hydrogen

Explanation:

pH is a measure of the ion concentration of hydrogen in a solution.

In chemistry, it literally means power of hydrogen ions and it is a measure of the molar concentration of hydrogen ions in a particular solution, thus specifying the acidity, neutrality or basicity of chemical solutions.

Mathematically, the pH of a solution is given by

Hence, a solution with a pH of 7 is neutral.

Also, a solution with a pH below 7 is acidic but basic if it's pH is above 7.

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).
