How do you prepare Dragendorff's Wagner's and mayer's reagents reagent?
(Wagner's reagent is used to test for alkaloids). To prepare Wagner's reagent; Dissolve 2g of iodine and 6g of KI in 100ml of water. -Atolani Olubunmi, Nigeria
What reagent is used to detect glucose in a solution?
You are not supposed to use buret reagent to detect sugar carbohydrates in a solution. Buret reagent is used to detect proteins. Try using iodine ( I2KI)
What is logol solution for?
If you think to Lugol, this solution is used as antiseptic, disinfectant, source of iodine, reagent for starch detection, reagent to detect some microbes, etc.
What organic molecule does iodine test for?
They test for carbohydrates. The Iodine reagent tests for starch. The Benedict's reagent tests for small sugars. Most carbohydrates are are made of sugar, and starch is a type of carbohydrate.
What reagent is used to test for starch?
The reagent that is used to test for starch is a mixture of iodine and potassium iodide in water, or an Iodine - KI reagent. If the reagent turns blue-black in color, then starch is present.
What chemical reagent tests for starch?
The simplest test is the iodine test.
Costituent of Wagner reagent?
iodine in potassium iodide
What reagent is used for starches?
Potassium Iodine (KI)
What chemical indicator do you use for starch?

Is iodine tincture same as weak iodine?
Tincture of iodine is a mixture of iodine dissolved in a potassium iodide solution. Iodine is the pure compound. At room temperate, iodine is quite unstable and tends to sublime. The tincture of iodine KI3 is used to stabilize iodine in certain experiments and as a reagent.
What is logol solution for?
