The pH scale is a measure of how acidic or basic a liquid substance is. The pH is calculated as a negative logarithmic function of the concentration of hydrogen ions, which are acidic by nature. A high concentration of h... More »

The pH scale is a logarithmic scale used to measure acidity. The pH scale measures how basic or acidic a substance is, and it ranges from 0 to 14. On the pH scale, a pH of 7 is neutral, less than 7 is acidic and higher t... More »

A pH scale chart includes a list of all the possible values along the pH scale and whether each value is acidic, neutral or basic. Each pH value has a color assignment that corresponds to its color in a pH indicator test... More »

Potential hydrogen, or pH, is the measure of the acidity or alkalinity of an aqueous solution. A solution is acidic if its pH is less than 7. If its pH is greater than 7, the solution is basic or alkaline. More »

The scientific term "pH" is an abbreviation that stands for "potential of hydrogen," which is a measure of the acidity or alkalinity of a solution.The term, which first came into use in 1909, is Germanic in origin and is... More »

The traditional measure of the natural pH of rainwater is around 5.7. However, considering all chemical compounds in the environment leads to modern scientists deducing that the pH is in the region of 5 to 7. More »

Sulfuric acid has a pH of 0.3 at a normality of 1 N, a pH of 1.2 at 0.1 N and a pH of 2.1 at 0.01 N. When using molar concentration, sulfuric acid has a pH of 2.75 at 1 millimole per liter, a pH of 1.87 at 10 millimoles ... More »
