Question

Chemistry...what is the difference between precipitation reaction and neutralisation.explain with example

Answer 1

some chemical reactions are accompanied by formation of precipitate. A precipitate is a solid substance formed by mixing two solutions. for example,
AgNO₃+NaCl give rise to AgClppt.+NaNO₃
When an acid and a base react with each other salt and water are obtained this reaction is called neutralization reaction.for example,
HCl+NaOH gives rise to NaCl+H₂O

Answer 2

Complement-fixation reactions are serological tests based on the depletion of a fixed amount of complement in the presence of an antigen- antibody reaction.
In neutralization reactions, the harmful effects of a bacterial exotoxin or virus are eliminated by a specific antibody.
