what is the name of the process when an acid and an alkali react?
Neutralization is the name of the process when an acid and an alkali react.
Please details
Neutralization is a chemical reaction that occurs when an acid and an alkali (or base) react with each other. In this reaction, the acidic and basic properties of the substances are neutralized, resulting in the formation of a salt and water.
When an acid and an alkali combine, the hydrogen ions (H+) from the acid react with the hydroxide ions (OH-) from the alkali to form water (H2O). At the same time, the remaining ions from both the acid and the alkali combine to form a salt.
The reaction can be represented by a general equation:
Acid + Alkali → Salt + Water
For example, when hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH), the resulting reaction is:
HCl + NaOH → NaCl + H2O
In this reaction, hydrochloric acid is the acid, sodium hydroxide is the alkali, sodium chloride is the salt formed, and water is produced as a byproduct.
Neutralization reactions have various applications in daily life and industries. For instance, antacids are used to neutralize excess stomach acid and relieve indigestion. Additionally, neutralization plays a crucial role in wastewater treatment to neutralize acidic or alkaline wastewater before it is discharged into the environment.
Overall, neutralization is an important chemical process that occurs when an acid and an alkali react, resulting in the formation of a salt and water.
