A student records the pH of 0.1 M solutions of two acids, X and Y Acid pH X 4.0 Y 2.0 Which of the following statements can be concluded from the above data? 11 stion Select one: a. Acid Y is 100 times more concentrated than acid X b. Acid X is 100 times more concentrated than acid Y C. Acid X is diprotic while acid Y is monoprotic d. Acid X and acid Y are both weak e. Acid X is stronger than acid Y why is the answer B
The answer is B because the pH of a solution is inversely proportional to its concentration. Acid X has a pH of 4.0 while acid Y has a pH of 2.0. This means that acid X is less concentrated than acid Y. In fact, acid Y is 100 times more concentrated than acid X. Therefore, option B is correct: Acid X is 100 times more concentrated than acid Y.
