What is a neutral solution?
100
substance that can donate a hydrogen ion
What is and acid
100
What are the three characteristics of a mixture?
1) Can be physically separated 2) Remain the same substances 3) Proportions may vary
100
What does the concentration depend on?
How much of the solute is dissolved in the solvent.
100
Use the concept of ions to explain how acids and bases are different.
Acids can give a hydrogen ion, while bases can accept one.
200
a solution containing more dissolved solute than is normally possible
What is a supersaturated solution?
200
substance that can accept a hydrogen ion
What is a base
200
What happens when ionic compounds are dissolved in water?
The compound splits into individual ions.
200
How can the solubility of a solution be changed?
Change in pressure or temperature.
200
Describe the properties of a base.
bases are slippery, bitter, and may burn skin if strong
300
a mixture in which particles are larger than those found in solutions- they turn the mixture cloudy and may settle over time
What is a suspension?
300
concentration of hydrogen ions in solution
What is the pH scale?
300
What happens when a covalent compound is dissolved in water?
Each individual molecule of solute is surrounded by solvent molecules.
300
what does solubility depend on?
molecular structure
300
Describe the characteristics of an acid
Acids taste sour, and produce an itching of prickling sensation.
400
the amount of solute dissolved in a solvent at a particular temperature
What is concentration?
400
the amount of the substance that will dissolve in a certain amount of solvent at a given temperature
What is solubility?
400
What happens to the physical properties of a solution when a solute is dissolved in it?
the freezing point is lowered and the boiling point is raised
400
Why don't water and oil mix?
Water is polar and oil is nonpolar
400
what are three safe methods to test acids and bases?
litmus paper, reaction with metal, and reaction with compound that has carbonate in it.
500
a solution that contains the maximum amount of solute
What is a saturated solution?
500
a solution that has a low concentration of solute
What is a dilute solution?
500
Describe the two parts of a mixture.
solute: dissolved into solvent solvent: has solute dissolved in it
500
What does "Like dissolves like" mean?
Polar dissolves polar and nonpolar dissolves nonpolar
