7. You are provided with two containers made up of copper and aluminiumYou are also provided with solutions of dil. Hcl, dil. HNO3, ZnCl2 and H20.[51In which of the above containers, these solutions can be kept? |
|
Answer» The solution of dilute HCl, dilute HNO3, ZnCl2and H2O can be kept in the container made of copper. Since copper is a less reactive metal and is placed below the hydrogen in activity series. Hence it does not react with HCl, HNO3ZnCl2and H2O. While aluminium is highly reactive metal and can reacts with these solutions.Thus container made of copper is suitable to keep the given solutions. |
