Dissolution.
sodium thiosulphate
Dissolving is not a chemical reaction; any chemical equation.
No, dissolving is a physical change
Thio: 1 mole S2O32- = 2 equivalent So Eq. mass = 0.5 * (molar mass)
Yes. A salt is an ionic compound and so dissolving (or hydrolyzing) it is a chemical reaction. An example with sodium chloride (table salt): NaCl (solid) -> Na+ + Cl- The charges on the products indicate that they are aqueous (in solution). Since the reactant breaks apart into it's products, this is a dissociation reaction.
Yes. Dissolving is a physical change because it does not change the chemical composition of either the solute or the solvent.

Dissolving is not a chemical reaction; any chemical equation.
The chemical symbol for sodium thiosulphate (hypo) is Na2S2O3•5H2O.
Dissolution is considered a physical process.
The chemical symbol for sodium thiosulphate (hypo) is Na2S2O3•5H2O.
Sodium Thiosulphate is Na2S2O3 and water is H2O.
Sodium chloride is dissociated in water: NaCl---------------------Na+ + Cl-
No, it is simply the water dissolving the sodium acetate, which is a physical change. There is a physical change when you introduce a seed crystal to the sodium acetate as the bonds in the chemical become different to form a solid. By adding water, you are just dissolving it and then allowing it to become supersaturated through heating.
There is NO chemical reaction at all when you dissolve NaCl into water. Dissolving is NOT chemical but a physical change of state.When however a reaction occurs, the original compound is called (one of) the reactant(s) and the compound(s) formed is (are) the product(s) of a chemical reaction.
