Explanation:
As you may know the pH scale is a scale that measures the degree of acidity of the substances. This scale has values ranging from 0 to 14.
On the pH scale, substances whose pH is less than 7 are classified as acidic, those with a pH greater than 7 are classified as basic, and those with a pH around 7 are considered neutral. The further away from number 7 the stronger the acid or base is. In this case, if a substance has a pH of 6, it means that that substance is a very weak, almost neutral acid.
