The lower the pH reading, the more acidic the solution. Readings from 0â7 are considered acidic, and numbers from 7.0â14 are considered basic, or alkaline. Pure water, in the very middle of the (logarithmic) pH scale, has a pH of 7.0, which is considered neutral.

Welcome to what I call the bullet bell curve. If you weigh every one of the bullets, and graph the weights, you'll see a distribution that follows a bell curve with the majority clustering fairly closely around the stated weight and a small number with the max weight variance isolated to the tails of the curve.
