Question

a solid precipitate is formed from the reaction of lead nitrate and sodium chromate. what would be the best method to separate this solid from the solution? ○ distillation ○ evaporation ○ filtration ○ sorting

Explanation:

To separate a solid precipitate from a solution, we analyze each method:

• Distillation: Separates mixtures based on boiling points (for liquids), not for solid - solution separation.
• Evaporation: Removes the solvent (liquid) to obtain dissolved solids, not for separating a solid precipitate from the solution.
• Filtration: Uses a filter medium to retain solid particles while allowing the liquid (solution) to pass through, ideal for separating a solid precipitate from a liquid solution.
• Sorting: Used for separating different types of solids based on physical properties (like size, color), not for solid - solution mixtures.

Answer:

filtration
