it feels crusty and sometimes powdery. It is very course in its un-ground form.
No
An aqueous solution of sodium chloride cannot be used to separate sodium from sodium chloride because both sodium and chloride ions are present in the solution. Sodium cannot be isolated from the solution without separate electrolysis techniques because it is also in the form of ions like chloride.
pure sodium chloride is white
No. Sodium chloride is polar, whereas diethyl ether is non-polar. Unlike solutes do not dissolve in unlike solvent. Only "like dissolves like".
No, sodium chloride is not soluble in toluene because toluene is a non-polar solvent and sodium chloride is an ionic compound. Ionic compounds like sodium chloride are generally soluble in polar solvents but insoluble in non-polar solvents like toluene.
Sodium chloride has two atoms in the formula unit (NaCl): sodium and chlorine.
Sodium chloride can be removed from solution by distillation. Boiling a solution of sodium chloride will cause the water to boil off and the sodium chloride to be left behind. If the water vapor is then condensed, the water obtained will be free of sodium chloride.
Sodium chloride is a compound.
Sodium chloride is not a cause of cancer.
Salts
Solid sodium chloride is not an electrolyte.Sodium chloride in water solutions or molten sodium chloride are electrolytes.
Sodium chloride is formed from sodium and chlorine.
