What is equivalent weight?

Equivalent weight (also known as gram equivalent) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance. The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. These values correspond to the atomic weight divided by the usual valence, for oxygen as example that is 16.0 g / 2 = 8.0 g.

What is acidity?

Acidity describes the amount of acid in a substance. An acid is a chemical that gives off hydrogen ions in water and forms salts by combining with certain metals. Acidity is measured on a scale called the pH scale. On this scale, a pH value of 7 is neutral, and a pH value of less than 7 to 0 shows increasing acidity.

How to Calculate Equivalent Weight for Acids?

Equivalent Weight for Acids calculator uses Equivalent Weight = Molar Mass of Acid/Acidity to calculate the Equivalent Weight, The Equivalent weight for acids formula is defined as the ratio of the molar mass of the acid to the acidity of the acid. Equivalent Weight is denoted by W _eq symbol.

How to calculate Equivalent Weight for Acids using this online calculator? To use this online calculator for Equivalent Weight for Acids, enter Molar Mass of Acid (M_acid) & Acidity (pH) and hit the calculate button. Here is how the Equivalent Weight for Acids calculation can be explained with given input values -> 14444.44 = 0.065/4.5.
