What is the main purpose of a burette in titration?
Correct answer: C. To deliver accurate volumes of solution
- A. To heat solutions
- B. To measure temperature
- C. To deliver accurate volumes of solution
- D. To measure mass
Explanation
A burette is used to add solution drop by drop. It helps in measuring precise volumes during titration. This ensures accurate calculation of concentration.

About Experimental Techniques in Chemistry
Separation methods are selected according to differences in solubility, particle size, volatility and sublimation behaviour. Filtration and crystallisation separate insoluble or dissolved solids, sublimation isolates suitable volatile solids, distillation separates liquids by boiling point, and solvent extraction transfers a substance between immiscible solvents.
