Solution and Explanation
- A pH of 1 indicates a strongly acidic solution, so solution B is strongly acidic.
- A pH of 13 indicates a strongly alkaline solution, so solution C is strongly alkaline.
- A pH of 4 is acidic but not strongly so, hence solution A is weakly acidic
. - A pH of 7 is neutral, so solution D is neutral.
- A pH of 10 is alkaline but weakly so, hence solution E is weakly alkaline.
