A water solution that has an excess of hydrogen ions; it turns litmus paper red, has a sour taste, and neutralizes bases to form salts
Any Compound that increases the number of hydroxide ions when dissolved in water; turns red litmus paper blue and reacts with acids to form salts.
A compound made up of the positive ion from the base and the negative ion from the acid
A reaction in which an acid reacts with a base to produce water, salt and heat energy
-dissociate in water, producing positive and negative ion
A pH of 7.
measurement system used to indicate the concentration of hydrogen ions (H+) in solution; ranges from 0 to 14
Hydrogen Ion Concentration
A measure of how many hydrogen ions [H^(+1)] are present in a solution (pH = -log [H+])
A laboratory procedure in which a substance in a solution of known concentration is reacted with another substance in a solution of unknown concentration in order to determine the unknown concentration.
Hydroxide Ion Concentration
A measure of the amount of OH^(-1) ions in a solution (pOH = -log[OH-])
To make a liquid less concentrated
Swedish 1859-1927- ion is an atom carrying a positive or negative charge; salts contain ions
H3O+ ions, which form when an acid dissolves in water and H+ ions interact with water.
This theory defines acids as proton donors and bases as proton acceptors.
a substance that can behave either as an acid or as a base
A reaction of an acid with a base, yielding a solution that is not as acidic or basic as the starting solutions were.
Lewis Acid-Base Theory
An acid is an electron pair acceptor, and a base is an electron pair donor.
