What exactly is a soluble salt? and is there a certain process used to prepare it ?

Answer 1

Soluble salt is a salt that can dissolve in water. THere are different types of 'salts'. Sodium Chloride (i.e. table salt - the ones you put in your meals to spice it up) is the most common. It is found in the sea (that's why the sea is salty) - because there is sodium chloride in there, dissolved in the water.

There are other types of salts out there: http://en.wikipedia.org/wiki/Salt (see this for a general explanation)

How are they formed (i.e. the process used to prepare salts): the are formed by a reaction between certain substances. See below:

Salts are formed by a chemical reaction between:

A base and an acid, e.g. NH3 + HCl → NH4Cl.
A metal and an acid, e.g. Mg + H2SO4 → MgSO4 + H2.
A base and an acid anhydride, e.g. 2 NaOH + Cl2O → 2 NaClO + H2O
An acid and an basic anhydride, e.g. 2 HNO3 + Na2O → 2 NaNO3 + H2O
Salts can also form if solutions of different salts are mixed, their ions recombine, and the new salt is insoluble and precipitates (see: solubility equilibrium).

This may sound a little complication, but that's all there is to it. The are formed like mixing the ingredients of a cake (i.e. a an acid is like the sugar, and the base is like the flour).

I hope that helped!

Answer 2

All salts have a solubility. Its only a question of how much.

Solubility occurs because the ions are attracted to the polar ends of the water molecule.

Some salts have a very low attraction, and we call them insoluble, but a certain amount does dissolve.

Solubility also depends on temperature. For most salts, the higher the temp, the higher the solubility.

Answer 3

Solubility of Salts

IONIC SOLUTE - POLAR SOLVENT:

Dissolving a Salt Crystal:

When an ionic crystal such as NaCl is placed in water, a dissolving reaction will occur. Initially, the positive and negative ion are only attracted to each other. The water molecules are hydrogen bonded to each other. If the crystal is to dissolve, these bonds must be broken.

Negative chloride ions on the surface are attracted by neighboring positive sodium ions and by the partially positive hydrogen atom in the polar water molecule (See the graphic on the left).

Similarly, the positive sodium ions are attracted by both chloride ions and the partially negative oxygen atom in the polar water molecule.

A "tug-of-war" occurs for the positive and negative ions between the other ions in the crystal and the water molecules. Several water molecules are attracted to each of the ions.

Whether the crystal dissolves is determined by which attractive force is stronger. If the internal ionic forces in the crystal are the strongest, the crystal does not dissolve. This is the situation in reactions where precipitates form. If the attractions for the ions by the polar water molecules are the strongest, the crystal will dissolve. This is the situation in sodium chloride.

Answer 4

Soluble salt is a salt (an ionic compound) which is soluble in water. The common salt, also called table salt is sodium chloride. It is prepared by evaporation of sea water (which conains sodium chloride, potassium chloride, magnesium chloride etc.) in flat pans and is then purified by resolution in water and fractional precipitation using hydrochloric acid.

Some salts are insoluble in water and alcohol.

Answer 5

Sea salt is larger for you, tastes extra desirable and has much less processed chemical compounds. you could relatively use under you're able to with usual table salt. actually, in case you attempt to cut back your sodium yet nevertheless enable your foodstuff no longer style like crap, the sea salt is actual a thank you to pass. They promote it in diverse varieties. Rocks, which you grind up your self, cooking and baking. I advise getting the type you grind your self. you may get the shape of grinder than is somewhat high quality. way extra desirable than crappy previous table salt!
