Which of the following is a homogeneous mixture? (colloid, solution, suspension)
solution
Identify the solvent in a glass of lemonade
water
Whipped cream and milk are examples of what?
colloid
True or False: Heterogeneous mixtures include suspensions and colloids.
True
True or False: Once the solvent particles surround the ions they are said to be solvated.
True
The material doing the dissolving
solvent
The material being dissolved
solute
Concentration describes the actual amount of _____________ (solute or solution) for a given amount of solution.
solute
The term dilute describes a solution with ________ amount of solute.
relatively low
This contains large particles that will settle out
suspension
True or False: Table salt dissolves in water because the sodium and chloride ions are repelled by the water molecules.
False; They are attracted to the water molecules and pulled apart.
True or False: Dissolving salt in water requires a chemical reaction to break apart sodium chloride into its elements.
False; It is physical change, the water will still taste like salt
By doing this you can remove sand from drinking water
filtration
What is the term used to describe a solution with the maximum amount of solute that the solution can normally hold at a given temperature?
saturated
This contains at least one metal
alloy
By doing this, you can remove fine iron particles from baby formula
magnetism
By doing this, you can separate fuel from crude oil (both are liquids)
distillation
The process of pulling apart ions out of a solid ionic compound
dissociation
supersaturated
This contains particles that are too large to dissolve but too small to settle out
colloid
By doing this, you can use heat to remove excess water from maple syrup
evaporation
Explain the process of salt dissolving in water using the following terms: positive ends, negative ends, dissociation, attracted, apart, surrounded.
Salt(NaCl) is made of Na+ and Cl- ions. When the salt enters the water, dissociation happens when the positive ends of the water molecule attract the Cl- ion and the negative end of the water molecule attracts the Na+ pulling them apart. Eventually the water molecules completely surrounds the Na+ and Cl- ions.
How can you increase the speed of something dissolving? example: chlorine tablets in water
heat, increasing the temperature of the solvent
Term used to identify a solution that contains less than the maximum amount of solute that it could hold at a given temperature
unsaturated
What is the process of dissolving called?
solvation
