Answer 5

A special type of homogeneous mixture, solute + solvent

Question 6

Aqueous solution

Answer 6

A solution in which water is the solvent

Question 7

Concentrated

Answer 7

a solution with a relatively large quantity of solute dissolved per unit volume of solution

Question 8

Dilute

Answer 8

a solution with a relatively small quantity of solute dissolved per unit volume of solution

Question 9

Polar

Answer 9

A Covalent bond where atoms share electrons unequally, in other words one side has more electrons while the other side has less

Question 10

Non- Polar

Answer 10

In this type of covalent bond, atoms share electrons equally therefore there is an equal amount of force of the electrons between both sides

Question 11

Hydration

Answer 11

the process in which ions are surrounded by water molecules

Question 12

Dissociation

Answer 12

the separation of individual ions from an ionic compound as it
dissolves in water

Question 13

• Miscible

Answer 13

liquids that mix with each other in all proportions to form a solution

Question 14

Immiscible :

Answer 14

liquids that don’t readily mix

Question 15

Ions

Answer 15

any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions.
