Respuesta :
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.
