Solution Observe the solutions A and B. An equal amount of hydrochloric acid was added to both beakers. After, the pH of both solutions were measured and shown here. Which of the following is a correct conclusion we can make about these solutions? O Solution B contains more hydrrogen ions compared to Solution A O Solution A contains a buffer because it was unable to resist large changes in pH after addition of hydrochloric acid O Solution B contains a high concentration of hydroxide ions to neutralize the added acid O Solution B contains a buffer because it was able to resist changes in pH after addition of acid
