In an experiment 2.4g of iron oxide in reduction with hydrogen gave 1.68 g of iron. In another experimet, 2.7 g of iron oxide gave 1.89 g of iron on reduction. Which law is illustrated from the above data?

A

Law of constant proportions

B

Law of multiple proportions

C

Law of reciprocal proportions

D

Law of conservation proportions

Text Solution

Verified by Experts

In first experiment,
Mass of iron oxide = 2.4g
Mass of iron =1.68g
Mass of oxygen = 2.4 - 1.68 = 0.72
Ratio of masses of iron and oxygen `=(1.68)/(0.72)=7:3`
In second experiment,
Mass of iron oxide = 2.7 g
Mass of iron = 1.89g
Mass of oxygen = 2.7 - 1.89 = 0.81
Ratio of masses of iron and oxygen `=(1.89)/(0.81)=7:3`
The same ratio confirms that these experiments clarify Law of constant proportions.
