Which of the following statements is TRUE? *
In a suspension of oil and water, the oil sinks to the bottom of the container.
A suspension consisting of oil and water is considered a miscible mixture.
Soil settles at the bottom of the container because it is less dense.
Suspensions can be separated using filter paper.
You are given 60% ethyl alcohol. Which of the following statements is TRUE? *
Water is the solvent because water is the universal solvent.
Alcohol is the solvent because it is found in a higher concentration in the alcohol solution.
Water is the solute because it dissolved faster than alcohol.
Alcohol is the solute because it was dissolved by water in the solution.
Which of the following statements are FALSE? *
Suspensions have larger particles than colloids and solutions.
Suspensions with finer particles are able to scatter light.
Oil is denser than water, which is why it stays afloat.
Substances like oil, soil, and sand do not mix well with water.
What will happen to sugar when hot water will be poured into it? *
The sugar will disappear.
The sugar will dissolve.
The sugar will settle at the bottom.
The sugar will float on top of water.
What is the most abundant substance in a colloid? *
Dispersed phase
Dispersing medium
Colloidal filtrate
Immiscibles
Which of the following is NOT a characteristic of solutions? *
It is a uniform mixture.
It will scatter a beam of light.
It is stable over time.
The solute and solvent cannot be distinguished by the naked eye.
All statements about suspensions are true, EXCEPT: *
Suspensions are larger particles is visible to the naked eyes.
Suspensions are particles that settle out when left undisturbed.
Suspensions are homogeneous mixture and are invisible to the naked eye
A mixture of soil and water is an example of suspension.
Soda pop, whipped cream, and beaten egg whites are examples of what type of colloids? *
Emulsion
Sol
Aerosol
Foam
A mixture of salt and water is a colloid because: *
The particles of salt are big enough to be seen, allowing the beam of light to be seen as it passes the mixture.
The particles of this mixture can block some the light from passing through.
A mixture of salt and water sometimes exhibits Tyndall effect.
None of the above.
This is the property where two substances are not able to mix and form a homogeneous mixture. Typically, these substances would form two layers of substances. *
Solubility
Immiscibility
Tyndall effect
Heterogeneity
Mixing oil and water will result to a... *
...suspension where oil is at the bottom of the container.
...suspension where oil and water are evenly mixed throughout the mixture.
...suspension where oil floats on top of the water.
...suspension where oil will solidify in the mixture.
An example of an emulsion is milk. Why is milk categorized as emulsion? *
Because settling can separate the components of homogenized milk
Because settling cannot separate the components of homogenized milk
The particles of milk as a colloid are larger.
The particles of milk as a colloid are smaller.
Which of the following statements is TRUE? *
The particles of a colloid are smaller than the particles of a solution.
A filter paper can be used to separate the solvent and solute of a solution.
All types of suspensions can exhibit Tyndall effect.
Among the three kinds of mixtures, suspensions have the largest particles.
How does a mixture of soil and water appear right after mixing? *
It appears clear.
It appears cloudy.
It appears messy.
All of the above.Suspensions are mixtures containing larger particles that eventually dissolve in the solvent when left undisturbed. *
