Neutralization Reaction
A neutralization reaction is a chemical reaction in which an acid and a base react to form a salt and water. It is a type of double displacement reaction in which the positive ion of the base combines with the negative ion of the acid to form a salt, while the hydrogen ions from the acid combine with the hydroxide ions from the base to form water.
Key Concepts
- Acids and Bases: Acids are substances that release hydrogen ions (H+) in solution, while bases are substances that release hydroxide ions (OH-) in solution.
- Neutralization Reaction Equation: The general equation for a neutralization reaction is: acid + base → salt + water.
- pH Scale: The pH scale measures the acidity or basicity of a solution. A pH of 7 is considered neutral, while lower pH values indicate acidity and higher pH values indicate basicity.
Examples of Neutralization Reactions
Some common examples of neutralization reactions include:
- Hydrochloric acid and sodium hydroxide: HCl + NaOH → NaCl + H2O
- Sulfuric acid and potassium hydroxide: H2SO4 + 2KOH → K2SO4 + 2H2O
