Simple solution of sugar in water is an example of true solution. Particles of true solution cannot be filtered through filter paper and are not <a href="https://interviewquestions.tuteehub.com/tag/visible-1447103" style="font-weight:bold;" target="_blank" title="Click to know more about VISIBLE">VISIBLE</a> to naked eye.</p><p>Colloidal Solution is a heterogeneous mixture in which particle size of substance is intermediate of true solution and suspension i.e. between 1-1000 nm. Smoke from a fire is example of colloidal system in which tiny particles of solid <a href="https://interviewquestions.tuteehub.com/tag/float-992844" style="font-weight:bold;" target="_blank" title="Click to know more about FLOAT">FLOAT</a> in air. Just like true solutions, Colloidal particles are small enough and cannot be seen through naked eye.They easily <a href="https://interviewquestions.tuteehub.com/tag/pass-1148402" style="font-weight:bold;" target="_blank" title="Click to know more about PASS">PASS</a> through filter paper. But colloidal particles are big enough to be blocked by parchment paper or animal membrane.</p><p>blood, starch, ink : Colloidal Soln.</p><p>sugar sol., salt sol : true soln.</p><p></p></body></html> | |
