Understanding Solutions
A mixture containing a solvent and at least one solute and has the same properties throughout.
Solution
The measure of how much solute can be dissolved in a solvent at a given temperature.
Solubility
Compounds that react with metals and carbonates, taste sour, and turn blue litmus paper red.
Acid
A scale expressing the concentration of hydrogen ions in a solution.
pH Scale
What do bees collect to make honey?
Nectar
The part of a solution usually present in the largest amount.
Solvent
A mixture that has only a little solute dissolved in a certain amount of solvent.
Dilute solution
Compounds that taste bitter, feel slippery, and turn red litmus paper blue.
Bases
The reaction between an acid and a base.
Neutralization
How many wives did King Henry VIII of England have?
6
A substance that dissolves in other substances.
Solute
A mixture that has a lot of solute dissolved in a solvent.
Concentrated solution
The property of acids that mean they "wear away" other materials.
Corrosive
An atom of hydrogen that has lost its electron and is produced by acids in water.
Hydrogen ion (H+)
Benjamin Franklin was a key figure in the drafting of the United States Constitution. Which state did he represent during the Constitutional Convention in 1787?
Pennsylvania
A mixture containing small, undissolved particles that do not settle out. The particles are usually too small to be seen without a microscope but large enough to scatter a beam of light (e.g., fog in air).
Colloid
Saturated solution
A compound that changes when it comes into contact with an acid or base.
Indicator
A negative ion made of oxygen and hydrogen made when some bases dissolve in water.
Hydroxide ion (OH-)
In mathematics, what is the name for a number that is not a prime number and has more than two factors?
Composite number
A mixture in which particles can. be seen and easily separated by settling or filtration (e.g. muddy water).
Suspension
Name the three common factors that can affect solubility.
1. Pressure
2. Solvents
3. Temperature
True or False: Bases turn red litmus paper blue, and acids turn blue litmus paper red.
True
Any ionic compound that can be made from a neutralization reaction.
Salt
What is the scientific term for the “little brain” at the base of the brain that coordinates movement and balance?
Cerebellum
