Unit 2 - Solutions And Solubility

Question 1

What is a Solvent/solute/solution

Answer 1

Solvent = the substance that dissolves the other e.g. water/H2O

Solute= the substance that gets dissolved
E.g. salt

Solution = The combined mixture of the solvent(s) and solute(s)
e.g. H2O + NaCl

Question 2

What is polarity?

Answer 2

Polarity refers to the way molecules bond to eachother.

E.g. water has a high polarity compared to oil that has a low polarity

Question 3

Saturated solution def

Answer 3

Not able to dissolve any more

Question 4

Unsaturated solution def

Answer 4

Still able to dissolve

Question 5

Molar solubility def

Answer 5

The number of moles of solute that can be dissolved before it becomes saturated

Question 6

Solubility def

Answer 6

The ability for a given substance, the solute, to dissolve in a solvent

Question 7

Precipitate def

Answer 7

Process of conversion into solid by converting the substance into an insoluble form or a super-saturated solution
