The correct answer is option 2. When the pH of a solution is changed from 4 to 3, the hydronium ions increases by a factor of 10. pH is a scale used to measure the acidity or alkalinity of an aqueous solution. It can be used to calculate the amount of hydronium ions in the solution. It is expressed as: pH = - log [H+].
