What are the constituents of Karl Fisher reagent?
Karl Fisher Reagent Dissolve 762 g of iodine in 2,420 ml of pyridine in a 10 liter glass stoppered bottle, and add 6 liters of methanol. To prepare the active stock, add 3 liter of the foregoing stock to a 4 liter bottle, cool in ice bath. Add carefully 135 ml of liquid sulfur dioxide, collected in a calibrated cold trap,and stopper the bottle. Shake the mixture until homogeneous, and set aside for one or two days before use.
What is the use of pyridine free reagent in Karl fischer?
because pyridine is toxic...so amines are used in place of pyridine.......
How do you calculate Karl Fischer factor?
To calculate the Karl Fischer factor there are three factors that are required. The ml KF reagent used for sample, the factor mg H20/ml KF reagent and the weight in grams.
Can you use a common reagent to test all the compounds?
no
Can you use a common reagent to test all compounds?
No

What is the difference between Karl fisher and loss on drying?
Karl Fisher Titration measures only the water content in a product sample. Loss on drying measures the total loss in weight of a material as a result of drying.?æ

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)
