What are the key differences between volumetric and gravimetric analysis?

Volumetric analysis and gravimetric analysis are two ways to find how much of a substance is present in a sample.

Differences:

1. What is measured:
   • Volumetric analysis measures the volume of liquid used.
   • Gravimetric analysis measures the mass of a solid formed.
2. Main tools:
   • Volumetric uses burette, pipette, and flask.
   • Gravimetric uses balance, filter paper, and crucible.
3. Type of reaction:
   • Volumetric uses liquid reactions (titrations).
   • Gravimetric uses solid formation (precipitation).
4. Speed:
   • Volumetric is faster.
   • Gravimetric takes more time.
5. Accuracy:
   • Volumetric is accurate if done carefully.
   • Gravimetric is usually more accurate.

In short, volumetric analysis measures volume, while gravimetric analysis measures weight to find how much of a substance is present.
