The pH of an acidic solution is a measure of the concentration of the acid particles in the solution, with smaller values of the pH indicating higher acid concentration.In a laboratory experiment, the pH of a certain acid solution is changed by dissolving over-the-counter antacid tablets into the solution.In this experiment, the pH changes according to the equation , where x is the number of grams of antacid added to the solution.What is the pH of the solution after the addition of 0.05 grams of antacid tablet?
A)5.99
B)4.02
C)-0.85
D)4.29
E)5.14
