Discuss the problems addressed by reformers in the 1800s.

I assume that you are talking about the problems that were
addressed in the wave of reforms that started in the 1830s and 1840s.  This was a time
when the US economy and society was changing rapidly.  A group made up mostly of middle
class people, many of them female, started to try to reform various aspects of
society.

Some of the most important problems addressed
were:

• Lack of quality education.  Reformers like
  Horace Mann pushed to have more public schools with more qualified
  teachers.


• Slavery.  People like William Lloyd Garrison
  started pushing for the abolition of slavery.


• Lack of
  rights for women.  The Seneca Falls conference started the women's rights movement in
  1848.

There were other reforms during those
times, such as ones addressed at improving prison conditions and the conditions in
insane asylums.  There were anti-alcohol and anti-prostitution crusaders.  In short,
there were many, many problems that reformers were trying to
address.
