Question

state the true or false if false correct it
particles of suspension cannot be seen by naked eyes​

Answer 1

Answer:

$\bf \: false$

$\sf↪ \: the \: size \: of \: particle \: is \: bigger$

$\sf{than \: one \: nano \: meter}$

Answer 2

Answer:

$\huge\purple{ \bf{false \ \: }}$

$</p><p>\sf↪ \: the \: size \: of \: particle \\ \sf \: is \: bigger. \: \: \: \: \: \: \: \: \: \: \: \: \:$

Additional information:-

colloid:-

• It is a heterogeneous mixtute

• The solute particles do not dissolve but remain suspended through the bulk of the medium

• Colloids - Solutions in which the size of particles lies in between those of true solutions and suspensions are called colloidal solutions or simple colloids

Tyndall effect:-

• The Tyndall effect is light scattering by particles in a colloid or in a very fine suspension.

Suspension:-

• Suspensions are heterogeneous mixture of two or more substances.

• Particles of solute do not dissolve in solvent rather they remain suspended in bulk throughout.

• The size of particles of suspension is large enough to be visible from naked eyes. They are greater than 1 nanometre (10^-9metre).

True solution:-

• True Solution is a homogeneous mixture of two or more materials.

• particle size of less than 10-9 m or 1 nm dissolved in the solvent.

Example:-

• Simple sugar solution in water.

• Particles can not be isolated from true solutions by using filter paper which is also not apparent to the naked eye.
