Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question

Acid Structure and Relative Acidity
The strength of an acid, HA, is often determined by the
strength and polarity of the H-A bond. In general, a
weaker and more polar bond leads to a stronger acid.
Part A
For binary acids of elements in the same group of the
periodic table, the H-A bond strength decreases down
the group, so acidity increases.
Rank the following compounds in order of decreasing acid strength using periodic trends.
Rank the acids from strongest to weakest. To rank items as equivalent, overlap them.
For binary acids of elements in the same row of the periodic
table, the polarity of the H-A bond increases from left to
right (as the electronegativity of A increases), so acid
strength increases.

Help
For oxoacids, acid strength increases with the oxidation
number of the central atom. If the oxidation number is the
same, acid strength increases with the electronegativity of
the central atom.
