Please help me solve this problem. I do not need just an answer, but a correct solution. If it takes 1.0 gram of solid NaOH (a strong base) to change the pH of a solution containing a strong acid from 1 to 2, how much solid NaOH (in g) would be needed to change the pH of this solution from 2 to 3? You may assume that there is no change in the volume of the solution.
