Water dissolve salts by neutralizing the ionic bond holding them together. Dissolved salts form cations (positively charged ions) and anions (negatively charged ions). The process of water surrounding an ion is called hydration.

∙ 11y agoDepends what salt you're on about, NaCl, KNO3, CuCO3, CH3COONa, FeI3 ???
Anyway the answer to way a salt is or isn't soluble is to do with the equation...
ΔG = ΔH - TΔS. ΔH is enthalpy and determines whether something is kinetically stable, ΔS is entropy and determines if something is thermodynamically stable hence T for temperature. ΔG is free energy and if it is negative then there is enough energy left over for the reaction to proceed, take NH4SO4 as an example it is actually an endothermic process to dissolve NH4SO4, this means ΔH is positive, but of course dissolving an ionic compound decreases the enthalpy dramatically, meaning Δs is positive TΔS > ΔH. This means ΔG is negative and the substance can dissolve. Of course somethings like the carbonate ion have much higher hydration and lattice enthalpies, so ΔH > TΔS, this makes ΔG positive and hence copper carbonate is not soluble.

How fast does sugar dissolve in water and how fast salt dissolve in water?
The amount of time and speed it takes to dissolve sugar in water and dissolve salt in water depends on the amounts of salt and sugar, the amount of water, and the temperature of the water. The approximate time needed to dissolve the sugar and salt in water is 25 minutes.
What type is substances dissolve easily in water?
Water is called "the universal solvent" because many, many substances can dissolve in it. However, there are some that can dissolve easier than others: salt and sugar are some of the quickest. Liquids and liquid chemicals also "dissolve" very easily in water, i.e. the combine with water molecules to create a solution. Hope this helped!!
Which dissolves in hot water salt or sugar?
Both sugar and salt dissolve in hot water. However because sugar has OH groups it is polar and more easily dissolved than salt
What types of molecules dissolve easily in water?
Polar molecules and ions dissolve easily in water
Can water dissolve more sugar or salt?
More sugar can dissolve in water than salt.
What will dissolve salt?
Water dissolve easily salt.
Why cant salt dissolve in water?
it can, polar water molecules easily dissolve polar molecules, or ionic compounds such as salt.
What does sodium chloride dissolve into?
Salt is easily soluble in water.
Is salt easily dissolve faster in water than sugar in water?
babe
What is the source of salt why it dissolve in water?
Salt is easily dissolved in water because both are polar compounds.
Why does salt dissolve in a solevant?
Because salt is an ionic compound is easily dissolved in water.
What kind of material does water dissolve most easily?
itself/salt/sugar.
Does water and salt dissolve?
No, but salt does dissolve in water.
Do you have to leave water with salt in the sun to dissolve?
Salt (NaCl) is easily dissolved also in cold water; but the solubility is enhanced by increasing the temperature.
Which will dissolve in water salt sand or gravel?
Salt will dissolve in water
Why does salt dissolve?
Sodium chloride is dissolved in water because is a polar, ionic compond.
Does sugar dissolve quicker in tap water than salt water?
Yes- this is because tap water is largely already unsaturated, making the sugar easier to dissolve. Salt water already has had salt dissolved into it, therefore making the water dissolve sugar more easily when it has had nothing else saturated into it. Hope that this helps! X
