a molecule that donates 2 hydrogen ions

Question 9

ethanoic acid/acetic acid/vinegar molecular formula

Answer 9

CH3COOH

Question 10

sulfuric acid

Answer 10

H2SO4

Question 11

carbonic acid

Answer 11

H2CO3

Question 12

nitric acid

Answer 12

HNO3

Question 13

hydrofluoric acid

Answer 13

HF

Question 14

strong acid/base

Answer 14

if added into aqueous solution, it will dissociate or ionise completely

Question 15

weak acid/base

Answer 15

will dissociate or ionise partially in their aqueous solution

Question 16

hydronium ion

Answer 16

H3O+

Question 17

hydrogen bromide

Answer 17

HBr; acid

Question 18

phosphoric acid

Answer 18

H3PO4

Question 19

how does ocean acidification work?

Answer 19

CO2 reacts with water to form H2CO3 which eventually breaks down into H+ and HCO3-; these H+ ions decrease the ocean’s pH

Question 20

bicarbonate

Answer 20

HCO3; weak base

Question 21

difference between concentrated acid/base and strong acid/base

Answer 21

concentrated refers to acid/base molecules whereas strong acid/base refers to its ability to completely dissociate

Question 22

list 4 examples of strong acids

Answer 22

HCl, HBr, HNO3, H2SO4

Question 23

ammonia

Answer 23

NH3; weak base

Question 24

sodium hydroxide

Answer 24

NaOH; strong base

Question 25

list 3 strong bases

Answer 25

NaOH, KOH, LiOH

Question 26

potassium hydroxide

Answer 26

KOH

Question 27

lithium hydroxide

Answer 27

LiOH

Question 28

electrolytes

Answer 28

a substance that conducts electricity when melted or dissolved in a substance

Question 29

why are acids and bases electrolytes?

Answer 29

they dissociate into positive and negative ions meaning they can conduct and electrical current

Question 30

electrical conductivity

Answer 30

the degree to which a material conducts an electrical current
