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 »

The pH of pure water at 25 degrees Celsius is very close to 7. This pH value indicates that water is neutral, meaning that it is neither acidic nor basic. Acids have pH values lower than 7, and bases have pH values highe... More »

Bleach has a pH value of around 12 or 13. The pH scale is used as a measure of the acidity or basicity of solutions in which the solvent is water. Solutions with a pH value of 7 or less are acidic, while those above this... 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 »

Fresh milk has a pH value that is typically between 6.5 and 6.7, making it slightly acidic. A pH greater than 6.7 indicates that the udders producing the milk are inflamed by pathogens, and milk with a pH lower than 6.5 ... More »

A neutral pH level is a value of seven on the pH scale. This number lies at the center of the scale and is the value that is associated with pure water. A pH level below or above seven indicates that the liquid is either... More »

In chemistry, the main difference between pH and pKa is that pH tells the level of hydrogen ions in a certain medium while pKa value indicates the degree at which an acid dissociates or the side at which equilibrium is f... More »
