acids/bases

Question 1

acids

Answer 1

proton donors
has excess H+ ions the more the H+ ions the more acidic

Question 2

properties of acids

Answer 2

sour sharp taste, corrosive, electrolytes- electricity,

Question 3

how many common acids are there

Answer 3

8

Question 4

Organic acids

Answer 4

some are organic or contains carbon eg. citric/ ethanoic/malic acid

Question 5

Mineral acids

Answer 5

anions in the acids found the minerals in the earths crust found in rocks/minerals

Question 6

Bascity of acids

Answer 6

the amount of H+ ions that can potentially be produced per acid molecule

Question 7

List all bascity

Answer 7

Monobasic- 1 H+ ion per acid molecule (HCl)
Dibasic- 2 H+ ions per acid molecule (H2SO4)
Tribasic- 3 H+ ions per acid molecule (H3PO4)

Question 8

strong acids

Answer 8

completely ionised in aqueous solution

Question 9

weak acids

Answer 9

partially ionized in aqueous solution

Question 10

example of strong/weak acids

Answer 10

HCl is a strong acid because it dissociates almost completely. By contrast, a weak acid like acetic acid (CH3COOH) does not dissociate well in water – many H+ ions remain bound-up within the molecule.

Question 11

ammeter

Answer 11

measure current reading stronger acid because there are more ions so it will ionize readily
