What is the general rule for determining solubility?
Organic compounds solubility rules To determine solubility of organic compounds usually the rule Like dissolves like is applied. This means that a solute will dissolve best in a solvent that has the same or similar polarity.
How do you determine the solubility of a salt?
Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .

Is common salt soluble in water?
What are the solubility rules for ionic compounds?
| Solubility Rules for Ionic Compounds in Water | |
|---|---|
| Rule 1: | Compounds of NH4+ and group 1A metal ions are soluble. |
| Rule 2: | Compounds of NO3–, ClO4–, ClO3– and C2H3O2– are soluble. |
| Rule 3: | Compounds of Cl –, Br – and I – are soluble except those of Ag+, Cu+, Tl+, Hg22+ and Pb2+. |
Why Common salt is readily soluble in water?
At the molecular level, salt dissolves in water due to electrical charges and due to the fact that both water and salt compounds are polar, with positive and negative charges on opposite sides in the molecule.
What is the solvent for common salt?
water
The attraction between the Na+ and Cl− ions in the solid is so strong that only highly polar solvents like water dissolve NaCl well….Aqueous solutions.
| Solubility of NaCl (g NaCl / 1 kg of solvent at 25 °C (77 °F)) | |
|---|---|
| Liquid ammonia | 30.2 |
| Methanol | 14 |
| Ethanol | 0.65 |
| Dimethylformamide | 0.4 |
What happens to common salt when dissolved in water?
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
Why common salt is readily soluble in water?
Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions. The amount of a substance that can dissolve in a liquid (at a particular temperature) is called the solubility of the substance.
What factors affect the solubility of salt?
There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.
What are 4 factors that affect solubility?
There are four major factors that affect the solubility of gases inside liquids. Pressure, temperature, size and chemical reactivity between the liquid and gas. By increasing the pressure, we usually increase the solubility of the gas inside the liquid as per Henry’s law.
Which factor affect solubility of salt in water?
Solubility of solids (salts) in water is affected by temperature, common ion effect, diverse ion effect, pH, etc.
