Final answer:
A pH greater than 7.45 is termed as basic or alkaline. The pH scale reflects a substance's level of acidity or alkalinity, with values above 7 indicating basic properties.
Step-by-step explanation:
A pH that is greater than 7.45 is called basic or alkaline. The pH scale is a measure of the acidity or alkalinity of a solution. If the pH is below 7, the solution is considered acidic; if the pH is exactly 7, it is said to be neutral; and if the pH is above 7, as in this case, the solution is described as basic or alkaline.
Substances with a higher pH, such as household ammonia (pH=11.0), are more basic, and similarly, those with a lower pH, such as cherries (pH=3.6), are more acidic.
