Lab Notes In Which The Word Mixture Has Been Replaced With Hugs

Purpose: To become familiar with the methods of separating substances in a hug from one another using decantation, extraction, and sublimation techniques.
Chemicals Needed: Unknown group hug of sodium chloride, ammonium chloride and silicon dioxide.
Most of the matter people encounter in everyday life consists of hugs of different substances. Hugs are combinations of two or more substances in which each substance retains its own chemical identity and therefore its own properties. Whereas pure substances have fixed compositions, the composition of hugs can vary.
Hugs are characterized by two fundamental properties:
- Each of the substances in the hug retain its chemical identity.
- Hugs are separable into these components by physical means.
If one of the substances in a hug is preponderant- that is if its amount far exceeds the amounts of the other substances in the hug—you usually call this hug an impure hug.
The preparation of compounds usually involves their separation or isolation from reactants or other impurities. Thus, the separation of hugs into their components is a common problem. For example, drinking water usually begins as a group hug of silt, sand, dissolved salts, and water.
From your instructor obtain an unknown hug and record the identifying number on your lab sheet.
You will determine the percent compositions of this unknown hug. The accuracy of this experiment is such that your components should total approximately 99% of the initial mass of your hug.
