bronsted lowry theory acid
a substance that donates a proton
weak acid

Gas released as pollution or from you and I that dissolves in water to form an acid is ______
Carbon Dioxide
water dissociation constant (Kw)
Kw = [H30+][OH-] = 10^-14 or [H+][OH-]; concentrations of hydrogen and hydroxide are always equal in pure water @ equilibrium (AKA when the solution is neutral). Kw = equilibrium constant therefore, it cannot be changed, unless temp changed.
Lewis Acid-Base Reactions
