Final answer:
If a solution has a higher pH than another solution, it is more alkaline than the other solution.
Step-by-step explanation:
If a solution has a higher pH than another solution, it is said to be more alkaline than the other solution. A solution with a higher pH indicates a lower concentration of hydronium ions and is considered basic or alkaline. In contrast, a solution with a lower pH indicates a higher concentration of hydronium ions and is considered acidic. pH values less than 7 are acidic, pH values greater than 7 are alkaline, and a pH of 7 is considered neutral.
