Question

Activity
2.3
Take approximately 50 mL of water
each in two separate beakers.
Add salt in one beaker and sugar or
barium chloride in the second beaker
with continuous stirring.
When no more solute can be dissolved,
heat the contents of the beaker to raise
the temperature by about 5°C.
Start adding the solute again. Observations and conclusion on this activity​

Answer 1

Explanation:

(a) No, they will be different. Actually sodium chloride (salt) is a crystalline solid while sugar is a molecular solid. They dissolve to different extent. Sodium chloride is more soluble in water compared to sugar at a given temperature. (b) Upon cooling, solid solute will slowly start separating from the solution. In general, the solubility of a solid in a liquid increases with the rise in temperature and decreases as the temperature is lowered.
