Hydrospheric Chemistry Flashcards
1
Q
Amphoteric/Amphiprotic
A
A species that can act as both an acid and a base
2
Q
Levels of generality in acid-base definitions
A
Lewis > Bronsted-Lowry > Arrhenius
- A proton donor is by default accepting a lone pair of electrons but the opposite is not necessarily true.
3
Q
Arrhenius
A
Acids are H+ donors and bases are OH- acceptors
4
Q
Bronsted-Lowry
A
Acids are proton donors and bases are acceptors
5
Q
Lewis
A
Acids are electron pair acceptors and bases are donors
6
Q
Why does water make a good solvent for polar substances?
A
High polarity, high dipole moment and high dielectric constant.
7
Q
What if an acidic substance accepts a proton?
A
It is considered in that reaction to be a base.
8
Q
How to calculate pOH
A
14 (end of pH scale) - pH value
9
