Give an example where temperature affects solubility?
Answer:
The solubility of solutes is dependent on temperature. When a solid dissolves in a liquid, a change in the physical state of the solid, similar to melting takes place. Heat is required to break the bonds holding the molecules in the solid together. At the same time, heat is given off during the formation of new solute.
all solution's solubility is effected when heated
start adding salt to a glass of water, after a while u will notice no more will desolve. but when u heat the solution u will find that u can add more salt than u could originally.
wen u heat a liquid the mloecules get excited and make space for more molecules from the solute i.e. the material u desolve in the liquid
When the temperature of water drops below 32f it freezes, reducing it's solubility.
AgNo3 +NaCl -----------------> NaNo3 + AgCl
AgCl is not soluble in normal temperature because it rejects heat to make it soluble you need to low the temperature
Coffee is an example.
when you put the powder to a cup of hot water, there will be an increase in solubility.why? because an increase in temperature will increase the kinetic energy of both the solute and solvent particles which will lead to an increase in solubility
