Bonus
100
Contains a solvent and at least one solute
What is a Solution
100
Has a lot of solute dissolved in a certain amount of solvent
What is a concentrated solution.
100
3 properties of an Acid
What is tastes sour, reacts with metals and carbonates, and turns blue litmus paper red.
100
The pH of a solution is 7 and is ____________.
What is neutral.
100
This will tell you the difference between a clear colloid and a solution.
What is shine a flashlight through them. Light passes through a solution without scattering, but a colloid scatters the light.
200
Part of a solution that is present in the larges amount and dissolves other substances.
What is solvent
200
Measures the concentration of a solution
What is solute ------- x 100 = % solvent
200
When acids react with metal, they produce this.
What is hydrogen gas.
200
The reaction between a base and an acid.
What is neutralization
200
This is how the effects of pressure on the solubility of gases is related to the scuba diving condition known as "the bends."
What is the solubility of gas decreases with decreased pressure. When scuba diving as you come up the pressure decreases and so does the nitrogen's solubility; if rising too fast, bubbles can form in the blood- this is the bends.
300
Contains larger particles than a solution. The particles are still too small to be seen easily, but are large enough to scatter a light beam.
What is a colloid
300
measure of how much solute can dissolve in a solvent at a given temperature
What is solubility
300
a compound that changes color when in contact with an acid or base.
What is an indicator
300
Are produced in water and are the cause of the properties of an acid.
What is hydrogen ions.
300
Comparing the particles formed in a water solution of an acid with those formed in a water solution of a base.
What is an acid forms H+ (hydrogen ions) in a water solution; a base forms OH- (hydroxide ions) in a water solution.
400
Lowers the freezing point and raise the boiling point of a solvent.
What is a solute.
400
The factors that affect the solubility of a substance
What is pressure, the type of solvent, and temperature
400
The properties of a base.
What is tastes bitter, feels slippery, and turns red litmus paper blue.
400
A base produces this when in water and is responsible for the bitter taste an slippery feel of bases, and turns red litmus paper blue.
What are hydroxide ions
400
If you have 1,000 grams of a 10% solution of sugar water, how much sugar is dissolved in the solution?
What is 100 grams
500
Conducts an electrical current when dissolved in water.
What is an ionic compound, like NaCl.
500
has more dissolved solute than is predicted by its solubility at the given temperature.
What is supersaturated solution
500
___________ & ___________ have many uses around the home and in industry.
What is acids & bases
500
A low pH indicates that the concentration of _______ _________ is big. In contrast, a high pH indicates that the concentration ________ ______ is low.
What is hydrogen ions.
500
You have and unknown solution. You want to know whether the solution is an acid or a base. First list some of the known properties of acids and bases. Then describe a method of determining whether the solution is an acid or a base.
What is Acids taste sour, react with metals and carbonates, turn blue litmus paper red; bases taste bitter, feel slippery, turn litmus paper blue. You could dissolve the solution in water. If it produces hydrogen ions (H+), it is an acid. IF it produces hydroxide ions (OH-), it is a base.
