What are the factors that affect the solubility of a 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 determines the solubility of salt in water?

Most sulfate salts are soluble. Important exceptions to this rule include CaSO4, BaSO4, PbSO4, Ag2SO4 and SrSO4 . Most hydroxide salts are only slightly soluble. Hydroxide salts of Group I elements are soluble.

What is unique about the solubility of sodium chloride?

The attraction between the Na+ and Cl− ions in the solid is so strong that only highly polar solvents like water dissolve NaCl well.

What are the 3 main factors that affect solubility?

Factors affecting solubility

• Temperature. Basically, solubility increases with temperature.
• Polarity. In most cases solutes dissolve in solvents that have a similar polarity.
• Pressure. Solid and liquid solutes.
• Molecular size.
• Stirring increases the speed of dissolving.

How does the size of solute affect the solubility of a substance?

Size of the particles — When a solute dissolves, the action takes place only at the surface of each particle. When the total surface area of the solute particles is increased, the solute dissolves more rapidly. Breaking a solute into smaller pieces increases its surface area and increases its rate of solution.

What is the factor that is responsible for salt like NaCl to dissolve in water easily?

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.

How does sodium chloride dissolve in water?

When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.

How do you determine the solubility of a salt?

Solubility indicates the maximum amount of a substance that can be dissolved in a solvent at a given temperature. Such a solution is called saturated. 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 .

Does sodium chloride have a low solubility?

Table salt, or sodium chloride (NaCl), the most common ionic compound, is soluble in water (360 g/L). That would be true if all we considered was the energy required to break the ionic interactions, as indicated by the fact that NaCl melts at 801 oC and boils at 1413 oC.

How does particle size affect solubility?

Decreasing the size of the particles increases the rate of dissolving. When you break up a large mass of solute into smaller pieces, you increase the surface area that is in contact with the solvent.
