Gravimetric analysis is a method in chemistry used to determine the amount of a substance by measuring the mass of a solid that is formed in a chemical reaction.
In simple terms:
- A substance in a solution is converted into a solid precipitate.
- The precipitate is collected, dried, and weighed.
- From its mass, the quantity of the original substance can be calculated.
Key Points:
- Based on precipitation, filtration, and weighing.
- Very accurate and reliable method.
- Used in food, pharmaceuticals, environmental, and industrial analysis.
In short:
Gravimetric analysis finds out how much of a substance is present by forming and weighing a solid product.
