Which of the following methods is used to separate particles from a suspension?
निम्नलिखित में से किस विधि का उपयोग निलंबन (Suspension) से कणों को अलग करने के लिए किया जाता है?
Detailed Solution & Logic
Evaporation/ वाष्पीकरण
Explanation
A suspension is a heterogeneous mixture in which insoluble solid particles are dispersed in a liquid. These particles are large enough to be seen and can settle down on standing.
To separate these solid particles from the liquid, filtration is used.
👉 In filtration, the mixture is passed through a filter paper:
-
Solid particles remain on the filter paper (residue).
-
Liquid passes through as filtrate.
हिंदी व्याख्या
निलंबन (Suspension) एक विषम मिश्रण होता है जिसमें अघुलनशील ठोस कण द्रव में फैले रहते हैं। ये कण बड़े होते हैं और कुछ समय बाद नीचे बैठ जाते हैं।
इन ठोस कणों को द्रव से अलग करने के लिए निस्यंदन (Filtration) विधि का उपयोग किया जाता है।
👉 निस्यंदन में:
-
ठोस कण फिल्टर पेपर पर रुक जाते हैं (अवशेष)।
-
द्रव नीचे निकल जाता है (निस्यंद)।
