following:
(a) KI
(b) HAS
Answers
Answer:
(b)has=What is the action of acidified potassium dichromate on acetaldehyde? Aldenudes can be oxidised to carboxylic acids. Oxidising agent and the reaction is normally carried out under reflex.Potassium dichromate, K
2Cr
2O
7, is a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications. As with all hexavalent chromium compounds, it is acutely and chronically harmful to health. It is a crystalline ionic solid with a very bright, red-orange color. The salt is popular in the laboratory because it is not deliquescent, in contrast to the more industrially relevant salt
(a)ki=I could find an exact procedure for it.(N. G. Klyuchnikov, Neorganicheskoi Sintez (Inorganic Synthesis), p.245-246.
Take 1 mass of potassium iodide, 1.5-2 mass of potassium dichromate, put them into a crucible, and close this crucible with an other crucible filled with water (to cool during condensation). During heating, the iodide formed will be sublimed and condensate onto the upper crucible bottom part.
The equation is: 4KI+2K2Cr2O7+O2=4K2CrO4 + 2I2
The oxidant is really the oxygen becasue the oxidation state of the chromium does not change.
