Strong acids and bases completely dissociate in water. classify
the following chemical compounds as strong acids, weak acids,
strong bases, and weak bases.
Strong acids and bases completely dissociate in water. Use the
table in the introduction to classify the following chemical
compounds as strong acids, weak acids, strong bases, and weak
bases.
Part A
H3PO4(aq) and KOH(aq)
Express your answer as a chemical equation including phases.
Part B
HI(aq) and LiOH(aq)
Express your answer as a chemical equation including phases.
Part C
HNO3(aq) and Cu(OH)2(s)
Express your answer as a chemical equation including phases.
Unlike strong acids and bases that ionize completely in
solution, weak acids or bases partially ionize. The tendency to
ionize (i.e., the ionic strength) of a weak acid or base can be
quantified in several ways including
Ka or Kb,
pKa or pKb,
and percent ionization.
Part A
Pyridine is a weak base that is used in the manufacture of
pesticides and plastic resins. It is also a component of cigarette
smoke. Pyridine ionizes in water as follows:
C5H5N+H2O⇌C5H5NH++OH−
The...
Unlike strong acids and bases that ionize completely in
solution, weak acids or bases partially ionize. The tendency of a
weak acid or base to ionize can be quantified in several ways
including
Ka or Kb,
pKa or pKb,
and percent ionization*.
*This assumes that species of equal concentrations are being
compared as percent ionization is affected by concentration.

A.) T or F : Strong electrolytes completely dissociate in water
to their contituent anions and cations.
B.) T or F: All atoms in a sample of gas move at 3R meters per
second, where R=8.314.
C.) T or F: Equal volumes of two different gases at STP contain the
same number of atoms.
D.) T or F: For an ideal gas, pressure and volume and directly
proportional.

1.Acids commonly dissociate to give hydrogen ions insolution
(H+), while bases dissociate to give hydroxide ions in solution
(OH-). Why is it important to know the difference between acids and
bases, in terms of safety? 2.Ionic bonds, covalent bonds and
hydrogen bonds all help to hold chemical entities together.
Distinguish between these types of bonding and explain which type
of bonding is responsible for matching the base pairs in DNA.
