AIM: To observe the effects of a copper catalyst on the reaction between zinc and sulfuric acid.
Equipment: Three test tubes test tube rack 10ml measuring cylinder dropping pipette granuated zinc copper turnings or powder dilute sulfuric acid h2so4
Method:
1 Add roughly the same mass of zinc to test tube 1 and 3
2 Add roughly the same mass of copper to test tubes 2 and 3
3 Add 5ml of dilute sulfuric acid to test tube . Note the rate of production of gas bubbles.
4 Add 5ml of the acid to test tube 2. Note the rate of production of gas bubbles.
5 Add 5ml of the acid to test tube 3. Note the rate of production of gas bubbles.
