Cooling Curves, Solutions And Solubility Curves

Question 1

Define solute

Answer 1

The solid that dissolves into a solvent to form a solution

Question 2

Define solvent

Answer 2

The liquid that the solute dissolves into to form a solution

Question 3

Define solution

Answer 3

The homogenous mixture formed when the solute had dissolved into the solvent

Question 4

Define saturated solution

Answer 4

A solvent where the most possible solute had been dissolved into it

Question 5

Define solubility

Answer 5

Maximum mass that can dissolve into 100g of solvent

Question 6

What is the effect of temperature on solubility of solids?

Answer 6

Higher temp means more solute can dissolve into solvent
More soluble

Question 7

Wffect of temperature on solubility of gases?

Answer 7

Lower temperature means higher solubility

Question 8

What are the solubility rules for salts?

Answer 8

GANGS

Group 1
Ammonium
Nitrates
Group 7 (except Pb and Ag)
Sulfates (except Ba and Ca)

E.g. Magnesium chloride is soluble but Barium chloride isn’t
