2.5 study guide Flashcards
1
Q
List the 5 properties of water
A
oxygen
hydrogen
carbon
chlorine
sodium
2
Q
cohesion
A
Hydrogen bonding between water (H2O) molecules
3
Q
adhesion
A
Hydrogen bonding between water (H2O) and other substances molecules
4
Q
Acid
A
more acidic = H3O+
5
Q
Base
A
more basic = OH-
6
Q
Buffers
A
Keep PH stable
7
Q
Explain how water’s polarity or ability to make hydrogen bonds gives it each property
A
Polarity makes water a good solvent, gives it the ability to stick to itself (cohesion), stick to other substances (adhesion), and have surface tension (due to hydrogen bonding).
