HNO3 is not used in redox titration because being a good oxidising ageant it oxidises the compound itself whereas HCL is a very volatile and it takes part in the reaction
therefore H2SO4 is used in the reaction
In the determination of iron in pharmaceutical preparations In the determination of iron in pharmaceutical preparations
It is probably because a part of the oxygen produced from the reaction of KmnO4 and HCl is used up in oxidising the HCl to Cl2 gas
H2SO4 is a strong acid and will deliver H(+) which will help to proceed the reaction much faster. Thereby, the sulphate-ions barely react in a redoxreaction. If we would take HCl for example, the Cl(-) ions can easily take part in a redoxreaction as a reductor.
iv done the titration and the preferred indicator for such a solution is phenalphaline, use a few drops to make it go a bright luminous pink and titrate till clear, not 'cloudy'
you have to use titration... http://www.avogadro.co.uk/miscellany/titration/titreset.htm or you can use the formula you have to use titration... http://www.avogadro.co.uk/miscellany/titration/titreset.htm or you can use the formula

500 x .50/1000 x 1/1 x 1000/6.0 = 41.7 = 42 mL HNO3
Nitric Acid is HNO3The chemical formula for nitric acid is HNO3
It would change your results because concentrated HCl is more acidic then H2SO4, therefore, there would be a larger change in pH quicker.
During a precipitation titration an insoluble precipitate is formed.Complexometric titration is a type of volumetry which use as titrants EDTA or other similar reagents.

u can use titration with EDTA or use flame atomic absorption.. but titration with EDTA is the easiest
