Question

Activity 6.2
Reactions of metals in water
Take a small piece of one of the metals provided for you. Use
sandpaper to clean the surface of the metal. You need to do this
because some of the metals may have reacted with the oxygen
in the air and formed a laver of metal oxide on the surface. This
would prevent the metal from being in direct contact with the water
2 Place the metal into a test tube of water.
3 Record your observations in a table and explain what has happened.
You may need to leave the metal to react for some time. If nothing
happens, you could try testing the metal again using hot water.
4 Repeat steps 1 to 3 for each of the other metals your teacher
has provided.
