You were given a mixture that might contain the following compounds. (Sand, NaHCO3, zinc powder, NaCl, sulfur powder). The following information might be useful to know about these materials. Only NaHCO3 can be dissolved in a hot water but not in a cold water and NaCl can be dissolved in both a hot and a cold water while sand, zinc and sulfur do not dissolve in water. However, zinc and NaHCO3 can react with strong acid such as HCl and produce gas molecules. Zinc can be attracted to a magnet while sulfur cannot.
Write a detailed procedure that allows you to purify this mixture.
