Sodium chloride is added for deicing.

The heat of dissolution for calcium chloride in water is greater compared with the same paremeter for sodium chloride; consequently the process of dissolution need more heat from the environment and the freezing point of the water solution is lower.

Sodium chloride is added to help soap precipitation.

Salt (table salt, rock salt, halite) is sodium chloride, NaCl. Salt added on the roads during the winter is generally also sodium chloride but calcium chloride may be used.

Ice melt faster when: - the temperature is higher - powdered salts as sodium chloride or calcium chloride are added

You will obtain a sodium chloride solution in water.

Sodium chloride is used to precipitate soaps from the solution.

Sodium chloride is added to increase the viscosity of the solution.

Salts (sodium chloride, calcium chloride) are added to reduce the melting point of ice; also the heat of dissolution contribute to the melting.

Generally it does not. Table salt is sodium chloride. However, some table salt has small amounts of calcium silicate added as an anti-clumping agent.

The sodium chloride will dissolve as it does in ordinary water.

0 % of sodium chloride is equal with no NaCl !

When calcium chloride is added to water, it lowers the freezing point. When spread on ice, it has the effect of melting the ice, and turning it to water. Calcium chloride is slightly less corrosive to metals that its "cousin", sodium chloride (salt), and so causes less rusting of cars, bridges, and guard rails.

Calcium chloride hasn't a good taste. But calcium chloride (as agent E509) can be added (of course in small amounts) to some foods and drugs.

Sodium chloride is dissociated in water in Na+ and Cl-. Sodium is an alkali metal.

Calcium chloride, or CaCl2, is an ionic salt comprised of calcium (C) and chlorine (Cl). CaCl2 disassociates when added to water into calcium cations and chloride anions.

water molecule will splits sodium chloride to sodium ions and chloride ions via hydrogen bonding.

A solution of sodium chloride will be formed. It will act as an electrolyte.

When calcium is added in aqueous solution of sodium carbonate white precipitates of calcium carbonate are produced.

An insoluble salt is formed--commonly called soap scum. Soap is the potassium or sodium salt of fatty acids. When calcium takes the place of the sodium or potassium, a calcium salt is formed. This takes the form of a whitish precipitate.
