Metals and acid Describe what happens when metals

Metals and acid * ** *** Describe what happens when metals react with acids State which metals produce bubbles when reacting with acid Compare the reactions of different metals with acid

What to do 1. Get sample of metal 2. Measure out 20 cm 3 of hydrochloric acid 3. When told – add metal to acid 4. Observe the reaction 5. Take the temperature after 60 seconds 6. Record (write) your observations down * ** *** Describe what happens when metals react with acids State which metals produce bubbles when reacting with acid Compare the reactions of different metals with acid

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 * ** *** Describe what happens when metals react with acids State which metals produce bubbles when reacting with acid Compare the reactions of different metals with acid

Interpreting our results Fastest Iron Zinc Magnesium Copper Slowest * ** *** Describe what happens when metals react with acids State which metals produce bubbles when reacting with acid Compare the reactions of different metals with acid

What is happening? hydrogen hydrochloric acid metal chloride metal * ** *** Describe what happens when metals react with acids State which metals produce bubbles when reacting with acid Compare the reactions of different metals with acid
