Cht 3: Water Flashcards
1
Q
Properties of water
A
Cohesive Adhesive High specific heat High heat of vaporization Lower density as a solid than liquid Excellent solvent
2
Q
Cohesive
A
Holding together like subs.
Causes surface tension: bugs to walk on water
3
Q
Adhesive
A
Sticking different things together
Ex. Tape and paper
Cohesion + adhesion = capillary action
4
Q
pH scale
A
Water molecules dissociate into h+ and oh- ions
Logarithmic: every unit 10x
Acid +base = salt + water
5
Q
pH. Neutral
A
Concentration of the 2 ions is equal
H+=OH-
pH is 7
6
Q
Acidic
A
Too many h+
Top scale
0-7
7
Q
Basic
A
OH-
7-14
