salt + hydrogen

Question 3

Reactivity series

Answer 3

potassium, sodium, lithium, calcium, magnesium, aluminium, carbon, zinc, iron, tin, lead, hydrogen, copper, silver, gold, platinum

Question 4

Which metal react with water in the reactivity series

Answer 4

potassium, sodium, lithium, calcium

Question 5

Which metals react with acids in the reactivity series

Answer 5

potassium, sodium, lithium, calcium, magnesium, aluminium, zinc, iron, tin, lead, copper

Question 6

Which metals are unreactive in the reactivity series

Answer 6

silver, gold, platinum

Question 7

Reactivity series required practical method

Answer 7

use a measuring cylinder to measure out 10cm3 of hydrochloric acid, place in a boiling tube, add
1 cm3 of each metal into separate tubes, observe the rate of hydrogen bubbles, faster bubble = more reactive, use this to rank the order of reactivity
