Na,Mg,Al,Ca,Cu,HCl(0.5M),distilled water
2Possible observations
If there is any reaction between metal and acid,metal and water
3Instructions
Mix metal with acid (and water) in test tube.If nothing happened,try to heat the test tube a bit.Record your observations in the following data table.
Metal HCL(0.5M) Water
Mg
Ca
Na
