Question

define
(a) colloid
(b) saturated solution​

Answer 1

Answer:

a) colloid = a homogeneous non-crystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle, and cannot be separated out by ordinary filtering or centrifuging like those in a suspension.

b) saturated solution = A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved. At 20°C, the maximum amount of NaCl that will dissolve in 100. g of water is 36.0 g. ... When 40.0 g is added, 36.0 g dissolves and 4.0 g remains undissolved, forming a saturated solution.

Answer 2

Answer:

a))Colloids are mixtures in which one or more substances are dispersed as relatively large solid particles or liquid droplets throughout a solid, liquid, or gaseous medium.

eg:muddy water, plaster, colored glass

b))A solution (with less solute than the saturated solution) that completely dissolves, leaving no remaining substances.

eg:soda
