Predict Ground limestone can be added to soil to make it less acidic. Would you expect the pH of
limestone in a water solution to be less than or greater than 7?

Respuesta :

Answer:

greater than

Explanation:

The pH of limestone in a water solution would be greater than 7.

pH is a measure of the degree of acidity or alkalinity of a solution. If we say that we want to make the ground soil less acidic, then we definitely have to add a basic substance.

A basic substance is one whose pH is greater than 7. The pH scale is organized in such a way that acids span from 0 - 6.9. A pH of 7 indicates neutral while a pH of 8 - 14 indicates a basic substance.

If limestone is basic, it must have a pH greater than 7.
