HETEROGENOUS MIXTURE SUSPENSION AND COLLOIDS Flashcards
WHAT ARE THE TWO TYPE OF HEEROGENOUS MIXTURE?
SUSPENSION
COLLOIDS
In a ________________________, undissolved
solutes are only suspended in the bulk of the solvent.
SUSPENSION
TRUE OR FALSE
IN SUSPENSIONS
The solutes form clumps or
layers that do not easily break apart into smaller pieces.
TRUE
IN SUSPENSION
there is no distinct layer from the solvent will be formed when the solute settles because of gravity.
false
true or false
The separate layer is usually seen at the top of the container.
Particles of a
suspension are larger than particles of a solution.
false
true or false
Sand in water is an example of a suspension.
true
give 3 examples of suspension
● mud (soil suspended in water);
● dust (solid soot and ash particles suspended in air); and
● blood (blood cells suspended in liquid plasma and water).
what is COLLOID
It is made up of a dispersedphase
(solute-like particles) and a dispersing medium
(solvent-like medium).
TRUE OR FALSE
IN COLLOIDS the
dispersing medium looks like homogeneous mixtures.
TRUE
TRUE OR FALSE
COLLOIDS are considered as in between the homogeneous nature of solutions and the
heterogeneous nature of suspensions.
TRUE
TRUE OR FALSE
COLLOIDS are NOT considered as in between the homogeneous nature of solutions and the
heterogeneous nature of suspensions.
FALSE
TRUE OR FALSE
Like solutions, colloids
appear homogeneous. But unlike solutions, their particles are not evenly distributed throughout the bulk of the medium.
TRUE
TRUE OR FALSE
Like solutions, colloids
appear heterogeneous. But unlike solutions, their particles are not evenly distributed throughout the bulk of the medium.
FALSE
WHAT ARE THE CLASSIFICATIONS OF COLLOIDS
Gaseous colloids - GAS DISPERSING MEDIUM
Liquid colloids - have liquids as the dispersing medium.
Solid colloids - have solids as the dispersing medium.
WHAT IS THE OURTH PHASE OF MATTER?
PLASMA
GIVE AN EXAMPLE OF GASEOUS COLLOIDS
liquid aerosol
SOLD AEROSOL
WHAT IS A solid dispersed phase suspended in a liquid is called ?
LIQUID SOL
WHAT IS A liquid suspended in another liquid is called
EMULSION
WHAT IS A gas suspended in a liquid is called?
LIQUID FOAM
WHAT IS A gas suspended in a solid is called ?
a solid foam.
WHAT IS A liquid suspended in a solid is called
a gel
WHAT IS A solid suspended in another solid is called
a solid sol.
________________is formed when the dispersed phase is a solid.
SOLID AEROSOL
A _______________ is formed when a liquid is the dispersed phase.
LIQUID AEROSOL
TRUE OR FALSE
ALL SOLUTIONS ARE HOMOGENEOUS
TRUE
TRUE OR FALSE
In a suspension, the particles are very large that they can be seen by the eyes.
TRUE
TRUE O FALSE
Sometimes, a suspension appears to be homogeneous.
TRUE
TRUE OR FALSE
When left alone, the particles of a suspension do not settle down.
false
true o false
in suspension
particles do not really dissolve.
TRUE
