Weight of copper oxide obtained by treating 2.16 g of …

In the first experiment:Weight of copper = 2.16 gWeight of copper oxide obtained on ignition = 2.70 g Percentage of copper in copper oxide In the second experiment.Weight of copper oxide = 1.15 gThus, the data illustrates the law of definite porportion as in both the experiments the percentage of copper and oxygen are same.

Copper Oxide

Cuprous oxide is more toxic for bacteria than cupric oxide because of the presence of one oxygen atom in cuprous oxide and two oxygen atoms in cupric oxide. a cuprous oxide is an active form of copper (I) oxide whereas cupric oxide is a more stable form of copper (I) oxide. cuprous oxide is more toxic because it can oxidise the phosphate groups of cellular components which are …
