A culture medium composed of carbon source, nitrogen source and minerals was sterilized at 120° for 15 minutes, inoculated with strains of the genus Streptococcus and then cultivated at 35° C for 72 hours under aeration and agitation. Subsequent to the cultivation, the resultant was subjected to water-washing and sieving to obtain crude glucan. The crude glucan was then dissolved in NaOH solution and centrifuged. The recovered filtrate was neutralized with HCl and then the insolubilized glucan was collected by centrifugation. The collected glucan was washed with water thoroughly until no chloride ion was detected in the waste water and then dried to form white purified glucan powder.

Solution
If water is added to an organic compound, the compound can dissolve in water if it is soluble or form a separate layer if it is insoluble. In some cases, the compound may react with water to form a new compound.
Water is a pure compound -- all of it is one kind of molecule: H2O.
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
Distilled water is a compound, H2O.it is a compound
Salt and water do not form a compound of any kind - neither decimal nor chemical.
Solution
Water is an oxide.
simple, compound, complex, compound-complex
Water vapor is a compound. It is made up of two different elements, hydrogen and oxygen, bonded together to form the compound H2O in gaseous form.
a compound
An ionic compound, specifically silver iodide.

They don't. The dissolving of salt in water is not the formation of a new compound, but rather merely creating a uniform mixture. It is not a new substance.
