Comments on how separate silica and sodium chloride

Physical Separation

In this experiment you will separate a three component mixture (containing sodium chloride, ammonium chloride and silicon dioxide) into the pure individual components. Knowing the mass of the original mixture and determining the mass of the pure components will allow you to calculate the percent by mass of each.

How to Separate Salt and Sand - 3 Methods - ThoughtCo

Dec 29, 2017 . Salt (sodium chloride or NaCl) is an ionic compound that is soluble in water. Sand (mostly silicon dioxide) is not. Pour the salt and sand mixture into a pan. Add water. You don't need to add a lot of water. Solubility is a property that is affected by temperature, so more salt dissolves in hot water than cold.

You may find some differences that can be used to separate them. Let's look at a few possibilities: sand and salt close up. Density: Sand is mostly silica (SiO2=silicon dioxide). If you look up the density of silicon dioxide, you find that the density is 2.2g/cm3. If you look up the density of sodium chloride, you find that it is.
