Lewis definition of bases
a hydrogen atom that can be donated
a substance that can behave as an acid or base (ex: water)
an acid that can donate only one proton (hydrogen ion) per molecule
an acid that can donate two protons per molecule
an acid able to donate three protons per molecule
The particle formed when a base gains a hydrogen ion
the particle that remains when an acid has donated a hydrogen ion
Kw for water

pH of acids
lower than 7 (the lower the pH the stronger the acid)
pH of bases
higher than 7 (the higher the pH the stronger the base)
[H+] of acids
[H+] is relatively high
[H+] of bases
[H+] is relatively low
[OH-] of acids
[OH-] is relatively low
[OH-] of bases
[OH-] is relatively high

An acid that ionizes completely in aqueous solution
an acid that is only slightly ionized in aqueous solution
common strong acids
HCl, HBr, HI, H₂SO₄, HNO₃, HClO₃, HClO₄
A base that dissociates completely into ions in solution.
A base that does not dissociate completely into ions in solution.
common strong bases

acid + base ↔ water + salt
A solution of known concentration is used to determine the concentration of another solution.
the solution that contains the precisely known concentration of a solute
the point in a titration at which an indicator changes color
The point at which the moles of H+ ions from the acid equals moles of OH- ions from the base.
A compound resulting from the formation of an ionic bond; also called an ionic compound.
A compound made up of the positive ion from the base and the negative ion from the acid
the salt produced from a strong acid and a strong base
a salt produced from a strong acid and a weak base
The salt produced from a weak acid and a strong base
A solution that resists changes in pH when limited amounts of acid or base are added.
prepared by mixing a weak acid or weak base with a salt of the acid or base.
