solutions

Question 1

solution propertie

Answer 1

solute and solvent cant be distinguished from each other

dissolved particles are too small to see

amount of dissolved solute can vary between solutions

Question 2

dissolution

Answer 2

process where a substance dissolves in another substance

Question 3

disassociation

Answer 3

many ionic substances dissolve in water

when an ionic substance is added to water, the lattice splits up

solute dissovles when ion-dipole attraction between the solute and water is strong enough

Question 4

types of solution

Answer 4

saturated - no more can be dissolved in solution

unsaturated - you can dissolve more in the solution

supersaturated - a solution that contains more solute than it should

Question 5

what happens when a supersaturated solution is disturbed

Answer 5

some of the solute will separate from the solution

Question 6

rules of solubility table

Answer 6

Each line represents the solubility of a substance

Anything on the line is a saturated solution

Anything below the line is unsaturated

Anything above the line supersaturated

Question 7

what happens when strong electrolytes (ionic substnaces or strong acids/bases) are dissolved in water

Answer 7

they are entirely present as independent ions

Question 8

what happens when weak electrolytes ( weak acids/bases) are dissolved in water

Answer 8

they are partly present as independent mobile ions (mainly molecules)

Question 9

what happens when non-electrolytes (covalent molecular substances) are dissolved in water

Answer 9

they do no produce ions and are entirely present as molecules.
