Question 1

Suspension

Answer 1

Suspension is a mixture in which large particles of a material are more/ less evenly dispersed throughout a liquid or gas.

Question 2

Colloid

Answer 2

Colloid is a mixture consisting of tiny particles that are intermediate in size compared to those of solutions or suspensions and that are suspended in a solid, liquid, or gas.

Question 3

Emulsion

Answer 3

Emulsion is any mixture of two or more Immiscible liquids in which one liquid is dispersed in the other.

Question 4

Solution

Answer 4

A solution is a homogenous mixture of two or more substances uniformly dispersed throughout a single phase.

Question 5

Solute

Answer 5

A solute is the substance that dissolves in the solvent

Question 6

Solvent

Answer 6

A solvent is the substance in which the solute dissolves

Question 7

Alloy

Answer 7

Alloy is a solid or liquid mixture of two or more metals.

Question 8

Heterogeneous mixture

Answer 8

A heterogenous mixture is made of different substances that remain physically separate. They always have more than one phase.

Question 9

Decanting

Answer 9

Decanting is the process for separation of mixtures by removing a layer of liquid.

Question 10

Immiscible

Answer 10

Immiscible is liquids that that do not mix with each other.

Question 11

Tyndall effect

Answer 11

The Tyndall effect is light scattering particles in a colloid or particles in a fine suspension.

Question 12

Polar compound

Answer 12

A polar compound is a molecule with a geometric arrangement of one side carrying a positive charge and the other side a negative charge.

Question 13

Hydrogen bonding

Answer 13

Hydrogen bonding is the intermolecular force occurring when a hydrogen atom that is bonded to a highly electronegative atom of one molecule is attracted to two unshared electrons of another molecule.

Question 14

Nonpolar compound

Answer 14

A nonpolar compound is a compound whose electrons are evenly distributed among its atoms.

Question 15

Solubility

Answer 15

Solubility is the maximum amount of a solute that will dissolve in a given quantity of a solvent at a given temperature and pressure.

Question 16

Concentration

Answer 16

Concentration is the amount of a particular substance in a given volume of solution.

Question 17

Unsaturated solution

Answer 17

An unsaturated solution contains less than the maximum amount of a solute that can dissolve.

Question 18

Saturated solution

Answer 18

A saturated solution is at a point where no more solute can be dissolved under the same conditions.

Question 19

Supersaturated solution

Answer 19

A supersaturated solution holds more dissolved solute than is required to reach equilibrium at a given temperature.

Question 20

Molarity

Answer 20

Molarity is a precise way of measuring concentration.

Question 21

Insoluble

Answer 21

Insoluble is incapable of being dissolved.

Question 22

Soluble

Answer 22

Soluble is able to be dissolved. Especially in water.

Question 23

Dilute

Answer 23

Dilute makes a liquid thinner or weaker by adding water to another solvent to it.
