Why are titrations using permanganate performed in an acid solution?
Titrations using permanganate ions are performed in acidic solutions because this will reduce KMnO4 completely to Mn2+.
What is idodine stain?
It is either iodine and it stains starch, or the other way around, starch that stains iodine, likely the former as it is biological. Starch or iodine can be used in chemical titrations also to indicate the presence of the other available in solution.
Why thiosulphate titration is called as redox titration?
A thiosulfate titration is mostly carried out to determine the amount of iodine present in the solution. In these reactions, thiosulfate ion acts as the reducing agent. This types titrations are often called as 'iodometric titrations'.
How do you write a equation for idometry and iodimetry titration reaction?
Iodometry & iodimetry Iodometry An application of iodine chemistry to oxidation-reduction titrations for the quantitative analysis in certain chemical compounds, in which iodine is used as a reductant and the iodine freed in the associated reaction is titrated

A student performed a series of titrations to find the concentration of an unknown acid The results of the titrations are shown in the data table What is the mean of this set of data?
0.984 M

Diff between gram's iodine and iodine?
iodine& grams iodine Gram's iodine is a solution of 2% iodine and 3% potassium iodide in 70% ethanol. Gram's iodine is also used as a forensic toxicology reagent for the detection of alkaloids, as a source of iodine for iodometric titrations, as an indicator for the presence of starch, and as a general laboratory source of iodine/iodide. This solution is laboratory grade, and not for medicinal use. Iodine is non metallic,dark gray,lustrous,solid element
How do you get pure dry iodine from a mixture of iodine and sand.?
Well every school kid knows about the 'cold finger' separation technique. Iodine changes from a solid straight to a gas when heated. It sublimes. So heat the sand/iodine mixture in a pyrex tube or flask which has a 'cold finger' inserted. The hot iodine gas will rise, hit the cold finger and form pure solid iodine crystals on the cold finger. Collect from the finger. This really is bog standard school kid chemistry.
What is titration and what is the purposeof titration?
Titration is the process of determining the concentration of a substance of a given solution using a known reagent. So types of titrations are neutralization titrations, red-ox titrations, gravimetric titrations and colorimetric titrations. According to the reagents available, the best type of titration should be determined.
How do you remove iodine stain from paper?
The iodine stain can be removed from the paper by washing the stain in plenty of cold water. Paper distillation can also be used to remove the iodine stain from the paper.
What is the use of iodine flask?
An Iodine Flask is essential an Erlenmeyer Flask with a stopper used for the wet chemical analysis "Iodine Determination" . This analysis is typically performed on fatty acids, oils and shellac varnishes.
Is iodine an irritant?
yes. usually iodine is diluted before use. If you get Iodine into your eyes immediately flush them with cold water. It will also cause a skin rash if not washed from the surface of your body as well.
