Miscibility and solutions

Question 1

homogenous mixture

Answer 1

a mixture of 2 or more chemical substance where the different components can’t be visually distinguished

Question 2

heterogenous mixture

Answer 2

a mixture of 2 or more chemical substances where the different components can be visually distinguished and easily separated by physical means

Question 3

solvent

Answer 3

the substance in which another substance dissolves to form a solution

Question 4

solute

Answer 4

the substance being dissolved

Question 5

miscibility

Answer 5

liquids which can be mixed together to form a single liquid

Question 6

immiscible

Answer 6

when liquids do not mix

Question 7

ionic/polar dissolves in

Answer 7

polar

Question 8

non-polar dissolves in

Answer 8

non-polar

Question 9

emulsifiers

Answer 9

another molecule is added that has both polar or ionic and non-polar components

Question 10

surfactants

Answer 10

molecules that consist of a polar and a non-polar component
(e.g soap, detergent)

Question 11

dissociation

Answer 11

water molecules bind to cations and anions forming secondary interaction : ion-dipole interactions

Question 12

Hydration

Answer 12

water molecules surround the dissociated cations and anions, forming a hydration shell to keep the ions away from bonding again

Question 13

Precipitate

Answer 13

an insoluble compound formed by the recombination anions and cations when solutions of ionic compounds are mixed

Question 14

soap scum

Answer 14

water with high concentrations of Ca2+ or Mg2+ ions can result in the formation of soap scum(precipitate)
