When pure sodium comes in contact with water (that includes moisture in the air), it undergoes a very vicious reaction. A lump of sodium about the size of a marble or smaller could easily catch fire in the reaction.
The resulting product is a very strong alkali called sodium hydroxide. Here is the balanced equation (remember Na is sodium):
2Na + 2H2O --> 2NaOH + H2
EDIT:
Also NaOH is ranked a 14 on the pH scale, which is one of the most strongest bases out there.

No. Sodium chloride is a neutral salt so if it's dissolved in pure water (pH 7) then the pH won't change (as it doesn't release or take in hydrogen ions)
Yes, sodium fluoride is a pure substance.
It is a pure substance as well as a compound
The easiest way of making sodium sulfate solution is by adding sulfuric acid to sodium hydroxide. If the pure material is required, then evaporate the water off.
Sodium chloride doesn't react with water; sodium chloride is dissolved and dissociated in water.

Pure Potassium or pure Sodium when mixed with water, creates an explosive reaction!!! ; ) .
In pure water, none.
Pure saline water is only a solution of sodium chloride in water.
Evaporating the water sodium chloride is obtained.
the pH level of sodium chloride (NaCl) is 7.
Nope. Sodium reacts violently with water. The pure stuff is normally stored under oil.
Yes, because there is no sodium in the solution.
Yes: If sodium fluoride is dissolved in water, the solution will conduct electricity, as will pure sodium fluoride if it is hot enough to melt.
No, pure ice (frozen water) does not have any sodium in it, because pure ice is just pure water that is frozen, and since water is H2O, and not H2NaO, ice doesn't have sodium in it. Ice will have whatever chemicals or other contaminants in it that were in the water before it was frozen. If the water had salt in it then the ice will be salty too.
Pure water, sodium chloride, sucrose, list goes on...
