colloids suspensions and solutions Flashcards
(20 cards)
What is a suspension?
A suspension is a heterogeneous mixture in which solid particles are dispersed in a liquid or gas but are not dissolved.
True or False: A colloid has larger particle sizes than a solution.
True
Fill in the blank: In a solution, the solute is completely __________ in the solvent.
dissolved
What is the main characteristic of a colloid?
It contains particles that are larger than those in a solution but smaller than those in a suspension.
Which of the following is an example of a suspension? A) Milk B) Muddy water C) Saltwater
B) Muddy water
What is the Tyndall effect?
The Tyndall effect is the scattering of light by colloidal particles.
True or False: Solutions can filter out solute particles using a filter paper.
False
What type of mixture is formed when particles do not settle over time?
Colloid
What is the main difference between a colloid and a suspension?
Colloids have particles that remain dispersed and do not settle, while suspensions have particles that will eventually settle out.
Which of the following is a characteristic of a suspension? A) Uniform composition B) Settling of particles C) Transparent
B) Settling of particles
Name a common example of a colloid.
Milk or fog.
What is the term for the liquid in which a solute is dissolved?
Solvent
Fill in the blank: A __________ is a homogeneous mixture of two or more substances.
solution
True or False: In a colloid, the dispersed phase is uniformly distributed throughout the continuous phase.
True
What happens to the particles in a suspension if left undisturbed?
They will settle at the bottom.
What is the dispersed phase in a colloid?
The particles that are distributed throughout the continuous phase.
Which type of mixture would you expect to be opaque? A) Solution B) Colloid C) Suspension
B) Colloid
What is an emulsion?
An emulsion is a type of colloid formed from the dispersion of one liquid in another liquid.
True or False: Solutions can exhibit the Tyndall effect.
False
What is the term for a mixture where particles are evenly distributed but not dissolved?
Colloid
