Neutralization Reaction Formula
The following formula is used to calculate the equivalent weight of an acid or base undergoing a neutralization reaction.
EW = (W/V) * N
- Where EW is the equivalent weight of acid or base (g)
- W is the present weight of acid or base (g)
- V is the total number of acid or base
- N is the normality
Neutralization Reaction Definition
A neutralization reaction is a chemical reaction that occurs when an acid reacts with a base to form salt and water. In this reaction, the positive ions from the base combine with the negative ions from the acid to create a neutral product. The reaction can be represented by the general equation: acid + base → salt + water.
Neutralization reactions are important for several reasons. Firstly, they are commonly used in various industries and laboratories to control pH levels. For example, in wastewater treatment plants, acidic or basic waste streams are neutralized to prevent environmental damage before they are discharged. Similarly, in the pharmaceutical industry, neutralization reactions are used to convert acidic or basic drugs into their neutral form, which is often more stable and suitable for administration.
Another important application of neutralization reactions is in the field of medicine. When an individual experiences heartburn or gastric acidity, it is due to an excess of stomach acid. Antacids, which are basic compounds, are used to neutralize the excess acid and provide relief. The neutralization reaction between the antacid and stomach acid helps to restore a more balanced pH in the stomach.
Neutralization Reaction Example
How to calculate a neutralization reaction?
- First, determine the weight of the acid or base.
Calculate the total weight of either the acid or base.
- Next, determine the volume.
Calculate or measure the volume of the same acid or base.
- Next, determine the normality.
You can use the calculator linked above to determine the normality.
- Finally, calculate the equivalent weight.
Calculate the equivalent weight of the acid or base needed for the reaction.
