How to separate a mixture of powdered sulfur, fine crystalline marble and kitchen salt.

How to separate a mixture of powdered sulfur, fine crystalline marble and kitchen salt. Make a work plan. Briefly describe each stage of the work and the expected results. Write down the formula and the substances mentioned.

Work plan:

1. Study the properties of all substances in the mixture.

2. Based on the difference in properties, choose a rational method for separation.

3. Separate the mixture using the necessary separation and subsequent separation methods.

Stages of work:

The separation of the mixture will be based on the solubility properties of the substances.

The salt will dissolve in the water, the sulfur will remain on the surface of the water, as it has poor wetting, and the marble will settle at the bottom of the container. Accordingly, the sulfur is separated by flotation; it will be enough to carefully collect it from the surface of the liquid. Separate the marble by filtration. Separate table salt from the solution by pairing until white crystals appear.

Formulas of substances: NaCl – salt, S – sulfur, CaCO3 – marble.
