Describing Acids and Bases
Acids and Bases in Solution
Digestion and pH
100
A well-mixed mixture that contains a solvent and at least one solute.
What is solution?
100
This type of solution occurs when so much solute is added that no more dissolves.
What is saturated solution?
100
This compound has a sour taste, although compounds in should never be tasted to determine their identity.
What is acid?
100
An atom of hydrogen that has lost one electron.
What is a hydrogen ion?
100
The organ in digestion that has a pH of 7.
What is the mouth?
200
Substance that is present in a solution in the smallest amount.
What is solute?
200
The measure of how much solute can dissolve in a solvent at a given temperature.
What is solubility?
200
This is the term used to describe how acids "eat away" at other materials.
What is corrosive
200
Any substance that produces hydrogen ions in water.
What is an acid?
200
These are the 2 parts of digestion.
What is mechanical and chemical digestion?
300
This is a mixture in which particles can be seen and easily separated by settling or filtration.
What is suspension?
300
Pressure, the type of solvent, and temperature are three things that affect this.
What is solubility?
300
The substance formed when an acid reacts with carbonates.
What is carbon dioxide?
300
Any substance that produces hydroxide ions in water.
What is a base?
300
Takes place with the help of enzymes.
What is chemical digestion?
400
It's particles are too small to be seen easily, but are large enough to scatter a light beam.
What is colloid?
400
This occurs when more solute is dissolved solute than is predicted by its solubility at the given temperature.
What is a supersaturated solution?
400
A compound that changes color when in contact with an acid or a base.
What is an indicator?
400
This tells you that the concentration of hydrogen ions is high.
What is a low pH?
400
This is released by the cells in your stomach during digestion.
What is hydrochloric acid?
500
This is a solution of chromium, nickel, and carbon in iron.
What is stainless steel?
500
At least two of the three factors that affect solubility.
What is pressure, the type of solvent, and temperature.
500
Two main characteristics of a base.
What is feeling slippery and tasting bitter?
500
This tells you that the concentration of hydrogen ions is low.
What is a high pH?
500
Produces salt and water.
What is a neutralization reaction?
