Question

what is the effect of temperature on the solubility of sodium chloride​

Answer 1

Answer:

If the temperature is increased then the kinetic energy of the particles increases and more space between the particles arises.

So, if the temperature of sodium chloride solution is arised then, more solute (sodium chloride) could me added to the solvent.

Hope it helps!!!

Answer 2

Answer:

solubility increases with increase in temperature

Explanation:

The effect of temperature on solubility depends on heat of solution explained by le-chatlier's principle.

heat of solution = hydration energy + lattice energy

if change in heat of solution is +ve then, solubility increases with increase in temperature.

if change in heat of solution is -ve then, solubility decreases with increase in temperature.

heat of solution of NaCl is +3.9(+3.88 KJ/mol).So, soubility increases with increase in temperature.
