The formula to calculate the Equivalent Weight (EW) is:
\[ \text{EW} = \left( \frac{\text{W}}{\text{V}} \right) \times \text{N} \]
Where:
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:
\[ \text{acid} + \text{base} \rightarrow \text{salt} + \text{water} \]
Neutralization reactions are important for several reasons. 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.
Let's assume the following values:
Using the formula to calculate the Equivalent Weight:
\[ \text{EW} = \left( \frac{10}{2} \right) \times 1.5 = 5 \times 1.5 = 7.5 \text{ g} \]
The Equivalent Weight is 7.5 g.
