Definition
Electron pair acceptor.
Term
Lewis Base
Definition
Electron pair donor.
Term
Auto-Ionization Reaction of Water
Definition
H2O(l) + H2O(l) = H3O+(aq) + OH-(aq)
Term
Water Dissociation Constant Kw
Definition

Helpful Log Rules
Definition

log(xy) = log x + log y

 

log xn = n log x and log 10x =x

 

-log 10-x = x
