Presentation transcript:

Metals and acid

What to do Get sample of metal Measure out 20cm3 of hydrochloric acid When told – add metal to acid Observe the reaction Take the temperature after 60 seconds Record (write) your observations down

Making observations bubbles fast reaction slow reaction no reaction very fast nothing happens very slow gets warm gets hot no temperature change hydrogen gas oxygen gas helium gas fizzing

Interpreting our results Iron Fastest Zinc   Magnesium Copper Slowest

What is happening? hydrogen hydrochloric acid metal chloride metal
