If the pH of a solution was 7 and you were to increase the hydroxide ion concentration 100x,what would the pH be? A)9 B)5 M C)1 × 10^-5 M D)700 M E)5

Question

Increasing the hydroxide ion concentration in a solution shifts the pH towards the basic side. A pH of 7 is neutral. Increasing the hydroxide ion concentration 100 times would decrease the hydrogen ion concentration by the same factor, moving the pH up by 2 units (since pH is logarithmic), resulting in a pH of 9.
