The Law of Constant Proportions applies to the:
स्थिर अनुपात का नियम ______ पर लागू होता है?
Detailed Solution & Logic
Pure chemical compounds/ शुद्ध रासायनिक यौगिक
The Law of Constant Proportions, also known as the Law of Definite Proportions, states that a pure chemical compound always contains the same elements combined in the same fixed ratio by mass, regardless of its source or method of preparation.
For example, in water (H₂O), hydrogen and oxygen are always present in a fixed mass ratio of 1:8.
This law does not apply to mixtures, because mixtures can have variable composition.
स्थिर अनुपात का नियम (Law of Constant Proportions) के अनुसार, कोई भी शुद्ध रासायनिक यौगिक हमेशा अपने अवयव तत्वों को एक निश्चित द्रव्यमान अनुपात में ही रखता है, चाहे उसे कहीं से भी प्राप्त किया गया हो या किसी भी विधि से बनाया गया हो।
उदाहरण के लिए, पानी (H₂O) में हाइड्रोजन और ऑक्सीजन का द्रव्यमान अनुपात हमेशा 1:8 होता है।
यह नियम मिश्रणों पर लागू नहीं होता, क्योंकि मिश्रणों की संरचना बदल सकती है।
