Sodium sulphate is a salt and as such is polar. The sodium part is a positive sodium ion which is then joined to a sulphate ion (negative). The + and - charges is what pulls the ions together to form sodium sulphate.
Water contains hydrogen bonds which means the H2O forms molecules with slightly negatively charged O atoms and slightly positively charged H atoms. Basically the big Oxygen atoms attract the tiny hydrogen atom's electron, making the O more -ve and the H more +ve.
This means when sodium sulphate is put in water, the -ve sulphate ion is attracted to the +e hydrogen atoms and the +ve sodium ion attracted to the -ve O atoms. This splits up the sodium sulphate and it becomes a sea of water molecules containing sodium hydroxide and hydrogen sulphide.

Sodium oxide soluble?
Sort of. Sodium oxide reacts with water to form sodium hydroxide, which is soluble.
Is sucrose soluble in sodium hydroxide?
No, sucrose is not soluble in sodium hydroxide without water.
Does sodium chloride dissolve in water?
Sodium chloride is very soluble in water; the obtained solution is saline water.
Which is more soluble in water sodium carbonate naphthalene or calcium carbonate?
Sodium carbonate is more soluble.
What is a good solvent for recrystallization of sodium benzoate?
none at all. i tried everything.
What is sodium benzoate solubility in water?
The solubility of sodium benzoate in water is 62.69 grams per 100 mL. Generally acids are not very soluble in water.
Is sodium benzoate soluble in sodium chloride?
Yes, Benzoic acid is a weak acid (pKa ~ 4.2) that will dissolve in weak base such as sodium bicarbonate (pKa ~ 6.4)
What are the ingredients of the effervescent tablet?
sodium bicarbonate, citric acid,sodium benzoate and water soluble flavour
Why initial products of the saponification of methyl benzoate soluble in water?
Saponification is a term used where soaps are formed as from fats and oils (triglycerides), methyl benzoate is a simple ester so here we may use the term hydrolysis, the reaction is performed in presence of NaOH so initial products are in ionic or salt form, sodium benzoate and sodium methoxide so are soluble in water.
Why is the sodium benzoate easily extracted into H20 while the original benzoic acid is not easily extracted into H20?
Because sodium benzoate is a salt and is soluble in water while benzoic acid is insoluble.
Why does benzoic acid precipitate out when the aqueous layer is acidified with HCl?
You're starting with something like sodium benzoate (depends on what base you used for the extraction step), which contains sodium ions (Na+) and benzoate ions (C6H5COO-). Ionic compounds like that tend to be soluble in water. When you add H+, you protonate the benzoate ion to make benzoic acid (C6H5COOH), which is a neutral molecule, and hardly soluble in water at all... so it precipitates.
Is sodium benzoate soluble in NaOH?
One gram of the salt is soluble in 2 ml of water, in 75 ml of ethyl alcohol, and in 50 ml of 90 % ethyl alcohol. The salt is insoluble in ethyl ether. Source is is a pdf from http://www.emeraldmaterials.com The complete link to the pdf file is found to the left of this answer under Web Links. It also includes the solubility in water a variety of temperatures.
Sodium benzoate solubility?
1gm in 2ml of water
Is sodium acetate soluble or insoluble in water?
Sodium acetate is soluble in water.
What is the chemical formula forsodium benzoate?
HCl(aq) + C6H5COONa(aq) --> C6H5COOH(s) + NaCl(aq)
Is sodium water soluble?
No, sodium will explode violently if touched by water. Salt, which is sodium-chloride, is soluble.
What will happen if you add Sodium Benzoate to chlorinated water?
Benzene
