How is the purity of a crystalized solid assessed?

Determine if crystalline sodium chloride and water are incompatible. If they are incompatible, state the hazardous conditions which would result from mixing the wastes.

Why do impure compounds normally have a lower melting point than the pure substance?

Write the salient features of the powder crystal method to determine crystal structure.

2. What important information does the melting point of a substance provide?

Why is it best to cool a solution slowly as a solid crystallizes? impurities are more likely to crystallize as well when done quickly the solid obtained will have a higher purity when done quickly no solid will form when done quickly the solvent could start to boil again when done quickly

Crystallization is used to? a) Separate soluble solid from a liquid b) Separate insoluble solid from a liquid c)Purify water for drinking d)Purify crude oil

Why is some water hard?

Water is a volatile liquid. True O False

However, there are many other commercially purchased inorganic and organic compounds that people routinely used in their households (or in their everyday lives). A list of 19 chemicals with common names are written below. Find each of these items in your home or in a local grocery and take picture of the container (if you do not have access to all of them choose at least 12 of them) and then complete the table below. For #16 and 17 you choose any other house hold chemical and complete the table. • Inorganic compounds 1) table salt, 2) baking soda, 3) washing soda, 4) photographic fixer, 5) Epsom salt, 6) alum, 7) chalk, 8) corn starch, 9) sand, 10) active ingredient in toothpaste or cleansing agent and disinfectant, 11) decolorizing carbon Organic compounds Naming of organic compounds will be discussed in details in Lab 10 however there are still some simple organic compounds that you encounter at your home. Organic compounds are compounds that contain at least one carbon with one…
