Acids and bases are classified as being either strong or weakdepending on the extent of their ionization in water. Strong acids and bases are completelyionized in dilute aqueous solution.НА — Н + АMOH → M + OHWeak acids and bases, however, show incomplete ionization in water; their ions exist inequilibrium with the undissociated acid or base.НА Н + АB + H;0 → HB + OHThe free acidity of an aqueous solution depends solely upon its hydrogen ion concentration.Pure water is very slightly ionized and is neither acidic nor basic, but neutral. The hydrogen ionand hydroxide ion concentration in pure water are equal. Both are 10 M.

Acids and Bases Onlin...
ACIDS, BASES, AND pH
OBJECTIVES: After completing this exercise, you should be able to:
1.
Estimate the pH of a solution given the concentration of the solution and the
degree of ionization.
2.
Use pH paper to determine the pH of a solution.
3.
Use a pH meter to determine the pH of a solution.
4.
Use titration techniques to standardize a solution of sodium hydroxide.
INTRODUCTION: According to Arrhenius, an acid is any substance which can provide
hydrogen ions (protons) in a chemical reaction, whereas a base is a substance capable of
providing hydroxide ions. Acids and bases are classified as being either strong or weak
depending on the extent of their ionization in water. Strong acids and bases are completely
ionized in dilute aqueous solution.
НА — Н + А
MOH → M + OH
Weak acids and bases, however, show incomplete ionization in water; their ions exist in
equilibrium with the undissociated acid or base.
НА Н + А
B + H;0 → HB + OH
The free acidity of an aqueous solution depends solely upon its hydrogen ion concentration.
Pure water is very slightly ionized and is neither acidic nor basic, but neutral. The hydrogen ion
and hydroxide ion concentration in pure water are equal. Both are 10 M. (Brackets used around
a symbol for an ion or a molecule should be read "concentration of"; [H"] means the
concentration of hydrogen ions.)
H,0-H+OH
[H1=[ OH ]= 10
It has been determined that in any aqueous solution at 25°C, the concentration of hydrogen ion
multiplied by the concentration of hydroxide ion equals 1014, whether the solution is acidic,
basic, or neutral.
[H' ][OH) - 10"
Thus, a 0.1 M solution of the strong base KOH would have a hydroxide ion concentration of 0.1
M, since concentration is so much greater than the hydrogen ion concentration it is 100%
ionized, and a hydrogen concentration of 1013. This solution is basic because the hydroxide ion
concentration is so much greater than the hydroxide ion concentration.
[OH] - 0.1 M
