so let's just broaden our understanding about the pH scale, The pH scale tells you the level of acidity of a substance. 7 is neutral, and any number under 7 is an acid, and anything greater than 7 is a base. the farther the number is away from 7, the stronger an acid or base is. for example, a substance with a pH of 14 would be a very strong base. Your answer is practically in this short paragraph. Hope this helped.
