pH Scale | U.S. Geological Survey - USGS.gov The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. pH Scale | U.S. Geological Survey - USGS.gov An official website of the United States government. Here's how you know
pH Scale - Elmhurst University The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6.

The pH Scale | Biology for Non-Majors I | | Course Hero The pH scale, which measures from 0 to 14, provides an indication of just how acidic or basic a substance is. Most parts of our body (excluding things like stomach acid) measure around 7.2 and 7.6 on the pH scale (a 7 is neutral on the scale). If foreign strong substances dramatically change this pH, our bodies can no longer function properly.

What is the pH Scale? - ReAgent Chemical Services The pH scale is a precise way of classifying the acidity, basicity or neutrality of a solution. As a logarithmic scale, 1 pH unit is ten times stronger, or ten times weaker, than the one below or above it, depending on its position: a pH of 4 is ten times more acidic than a pH of 5, but ten times weaker than a pH of 3.

Acids, Alkalis, and the pH Scale - Compound Interest A pH of spot on 7 denotes a neutral solution (neither acidic or alkaline). Any pH below 7 is acidic, whilst any pH above 7 is termed alkaline. Water molecules have the chemical formula H 2 O. However, these molecules are capable of splitting up slightly in solution, in H + and OH - (hydroxide) ions.
