Answer :
Final answer:
Solutions with pH values like 8.0, 8.9, 10.1, and 14.0 are considered as alkaline or basic.
Explanation:
Solutions with pH values like 8.0, 8.9, 10.1, and 14.0 are considered as alkaline or basic. The pH scale ranges from 0 to 14.
A solution with a pH of 7 is considered neutral. Solutions with a pH below 7, like 8.0 and 8.9, are considered acidic. Solutions with a pH above 7, like 10.1 and 14.0, are considered alkaline or basic. The pH value of a solution signifies its relative acidity or alkalinity based on its hydrogen ion (H*) concentration. In the context of the pH scale which ranges from 0 to 14, solutions with a pH of 7 are considered neutral. If the pH is lower than 7, it is acidic, and higher than 7, it is basic or alkaline. Therefore, all the solutions with the given pH values are alkaline since they all are higher than 7.
