What is the function of sulfuric acid in redox titration?
Sulphuric Acid (H2SO4) is used in the redox titration process because it provides the H(+) ions necessary for the reaction to occur more quickly whilst the sulphate(-) ions barely react during the reaction.
Nitric acid is very corrosive and a very strong acid. You can mix in water but remember add acid to the water and not water to the acid. When mixed with concentrated sulfuric acid it forms an excellent nitrating mixture for organic compounds. When doing a chloride titration with Silver Nitrate, Nitric acid is used to acidify and help the titration. There are many other uses also which involve mixing chemicals with nitric acid.
