|
|
|
Rate of stirring and size of sodium chloride

|
|
Volume, rate of stirring and size of sodium chloride
|
|
|
Volume, size of sodium chloride and temperature of water
|
Explanation:
Detailed explanation-1: -An increase in pressure and an increase in temperature in this reaction results in greater solubility.
Detailed explanation-2: -There are two direct factors that affect solubility: temperature and pressure.
Detailed explanation-3: -The rate of dissolving depends on the surface area (solute in solid state), temperature and amount of stirring.
Detailed explanation-4: -When a salt is dissolved in water, the temperature of solution decreases.
Detailed explanation-5: -1: Solubility curves for several compounds. Notice how the temperature dependence of NaCl is fairly flat, meaning that an increase in temperature has relatively little effect on the solubility of NaCl.
