I have a paper to write on types of reactions. Precipitation, acid-base, and oxidation-reduction reactions. We have to find and discuss and example of each reaction type that has industrial significance. Could you give me some direction?

Precipitation Reaction
This is based on the formation of insoluble substance (known as precipitate) from the reaction of two water soluble substances. A good example of precipitation reaction is between silver nitrate and sodium chloride:
AgNO3 + NaCl → AgCl(s) + NaNO3
AgCl is a white, curdy precipitate. The net ionic equation for the formation of AgCl is:
Ag+ + Cl- → AgCl
The industrial significance of this reaction lies in the fact that it can be used to analyze the amount of halides such as Cl- in certain samples such as water following the Mohr method. The sample is added with K2CrO4 as indicator, then it is titrated with standard solution of AgNO3. As AgNO3 is gradually added, AgCl forms. When all Cl- has been reacted ...

Solution Summary

Types of reactions are examined. Precipitation, acid-base, and oxidation-reduction reaction are the reactions in question.
