write any three characteristics of colloid Suspension and compound
Answers
SUSPENSION :-
⏹ suspension is a heterogeneous mixture.
⏺particles of suspension can be seen by naked eyes. they are bigger.
⏹ particles of suspension scatter when a beam of light passes through it and make it's path visible.
⏺ suspension is unstable means solute particles settle down if it's left undisturbed for sometime.
⏹ particles of suspension can be filtered by the process of filtration.
⏺examples of suspension - mud water etc.
COLLOID :-
⏺a colloid is also a heterogeneous mixture.
⏹particles of colloid can't be seen by naked eyes because they are very small.
⏺colloids also make visible path for the light passing through it and it's particles also scatters.
⏹colloids are quite stable, particles of colloid don't settle down if left undisturbed.
⏺colloids can't be filtered by the process of filtration.
⏹ examples of colloids - milk, foam, gel etc.
COMPOUND :-
⏹a compound is formed by the reaction of two or more elements.
⏺the constituents of a compound can be separated by only chemical reactions.
⏹the mass of a compound is the sum of mass of all elements that make it up.
⏺ examples of compound - salt (NaCl), carbondioxide (Co2) etc.
