Experiments with Copper Sulphate And Iron #experiment #science #Shorts

A student addd few pieces of aluminium metal to two test tubes A and B containing aqueous solutions of iron sulphate and copper sulphate. In the second part of her experiment, the added iron metal to another test tubes C and D containing aqueous solutions of aluminium sulphate and copper sulphate. In which test tube or test tubes will she observe colour change? On the basis of this experiment, state which one is the most reactive metal and why ?

The reaction between iron and copper sulphate solution represents which type of reaction ?

Three test tubes marked A, B and C are taken. In test tube A copper sulphate solution and iron are added. In test tube B, copper sulphate solution and zinc are added. In test tube C, iron sulphate solution and copper are added. In which test tube will the experimenter observe change and why?

Copper sulphate reacts with sodium hydroxide to form a blue precipitate of copper hydroxide and sodium sulphate. In an experiment, 15.95 g of copper sulphate reacted with 8.0 g sodium hydroxide to form 9.75 g of copper hydroxide and 14.2 g of sodium sulphate. Which law of chemical conbination is illustrated by this data ? Give reason for your choice.

The following materials are supplied to you : Stand, iron nail, test tube, copper sulphate solution and sand paper Decribe and activity to carry out the reaction between iron and copper sulphate and identify the type of reaction .
