A chemist makes two solutions. One is a 0.01-M HBr solution, and the other is a 0.01-M $CH_3COOH$ solution. The pH of the HBr solution is found to be 2. Would you expect the pH of the $CH_3COOH$ solution to be greater than or less than 2? O The pH of $CH_3COOH$ would be the same as that of the HBr because their concentrations are the same. O The pH of $CH_3COOH$ would be lower than that of HBr because a large fraction of HBr molecules does not dissociate. O The pH of $CH_3COOH$ would be greater than that of HBr because a large fraction of $CH_3COOH$ molecules does not dissociate. O The pH of $CH_3COOH$ would be lower than that of HBr because $CH_3COOH$ is a stronger acid.
