If the temperature is too low (below 55 degrees celsius), the interaction between the oxalate and the potassium permangante will move too slow as to be used as a practical lab experiment. *** Above 60 degrees celsius, oxalate acid begins to decompose, so its important to stay in this range If the temperature is too low (below 55 degrees celsius), the interaction between the oxalate and the potassium permangante will move too slow as to be used as a practical lab experiment. *** Above 60 degrees celsius, oxalate acid begins to decompose, so its important to stay in this range

Is sulfuric acid a reagent or not?
Sulfuric acid is a reagent.
What is a back titration?
A back titration is a form of titraiton in which an excess of standard reagent is added and then the reverse of the titration is carried out.
What is blank titration?
Types of titrations 1. Direct titration: analyte + titrant → product 2. Blank titration: titration of a solution not containing the analyte (check for errors) If the endpoint is unclear, we can use a . . . Back titration a. Excess of standard solution is added to analyte (and they react) - Step 1 b. A second standard titrates the excess (unreacted) standard - Step 2 Step 1: analyte + reagent 1 → product + excess reagent 1 Step 2: excess reagent 1 + reagent 2 → product

Why potassium iodate is added to potassium iodide in iodometry titration?
Iodometric titration means the titration of triiodide. Preparation of triiodide can be prepared by adding solid iodine to excess potassium iodide, however since iodine sublimes it is more difficult to weigh than potassium iodate. The triiodide would then need to be standardized with primary standard grade arsenious oxide. A better way is to weigh potassium iodate and add to a small excess of potassium iodide. The two ions (iodide and iodate) will also form the needed triiodide in an acidic environment. If the reagent is made fresh this way it can be used to standardize thiosulfate. Iodide iodate of known normality can also be used to titrate unknown concentrations of sulfite. For example, steam boiler treatment applications.

Where you can get sulphuric acid?
Battery acid, purchased at an automotive supply store, is approximately 35% sulfuric acid. You have to remove the water, the sulfuric acid abtained will not be as pure as reagent-grade sulfuric acid.
