Properties of Water & pH Flashcards
What are the four properties of water?
Cohesion
Moderation of Temperature
Floating of ice on liquid water
Acts as a solvent
What is a solvent
Dissolving agent of a solution
What is a solute
the substance that is dissolved by a solvent
What is a solution
-A homogeneous mixture of two or more substances
A mixture composed of more particles of solvent than solute
Solution
Polar molecules that are attracted to water
Hydrophilic “Water loving”, “Like dissolves Like”
Non-polar molecules that are not attracted to water
Hydrophobic. (ex. water and oil)
Substances that are nonionic and non polar
-cannot form hydrogen bonds, hydrophobic molecules
Substances that have more H+ than OH-
Acids
Has an increase hydrogen ion (H+) concentration in a solution
Acids
Acids have a
low pH below 7.
Bases are
substances that have more OH- than H+ (high pH)
Increased hydroxide in a solution, reduce the hydrogen ion
Bases
Substances that help maintain a constant pH
Buffers
Solutions made of weak acids and weak bases are called?
Buffers
Hydrophilic molecules “like” water because they are
polar
This property allows certain things to rest on top of water
Surface tension
The name of the compound when a strong acid and strong base are mixed together
Salt
This functional group is called either a ketone or an aldehyde
Carbonyl (C=O)
Which type of isomer creates mirror images?
Enantiomers
The ____ is the amount of heat/energy required to raise 1 gram of substance 1 degree
Specific Heat
This functional group is important in membranes and energy
Phosphate (OPO3 ^2)
This functional group can help stabilize proteins
Thiol/ Sulfhydryl (SH)
This functional group acts as a base
Amine/ Amino
