1)Describe pure sand and pure salt. Use a hand lens if available to get more detail. Type a description. a)sand b)salt 2)Investigate the dissolving properties of pure sand and pure salt. Which one will be caught in the filter paper if each substance was mixed with water and then filtered? Filter both separately if you are not sure. Devise a plan to get pure sand and pure salt in different piles from a 1 gram sample of the mixture. Include in your plan:

See explanation

Explanation:

A salt is made up of homogeneous particles while sand is made up of heterogeneous particles. Salt is a crystalline substance while sand is a coarse substance.

If salt and sand are mixed with water, salt forms a solution with water, hence, salt cannot be caught on filter paper. However, sand does not form any chemical specie with water hence it is caught on the filter paper as a solid.
