What happens when hexene reacts with cold neutral and dilute potassium dichromate?

One would expect that the reaction between an alkene and cold, dilute potassium dichromate is an oxidation to a bifunctional alcohol at the carbons in the double bond. The result is also called a vincinal diol or a glycol.
The reaction should be similar to the reaction of an alkene with cold, dilute potassium permangante, however, dichromate is a milder oxidizing agent and may not be as effective.
The mechanism for this reaction involves the formation of an intermediete 'ester' with the metal at the carbons of the double bond, breaking the double bond. The it can be shown that the resonance structure of the intermediete complex transfers electron density to the ester linkage and protonates from water at both of the ester sites completing the oxidation.

Chlorine gas plus cold dilute potassium hydroxide?
You will get a solution of potassium chloride and potassium hypochlorite.
What is the chemical reaction of aluminum oxide and dilute potassium hydroxide?
(*Warning!!Xb42 is a atomic chemical,so do not mix aluminum oxide and dilute potassium hydroxide!!*)
How is potassium hydroxide different from dilute nitric acid?
Potassium hydroxide is a powerful base with a pH of 14. Dilute nitric acid is a strong acid with a pH of between 0-1 usually.
How do you prepare 1 N potassium dichromate?
prepare a concentrated aqueous solution of di chromate and add solid KOH warm till orange colour change to yellow and then filter the solution the filtrate is allow to evaporate and get solid potassium chromate.
Which metals react with dilute hydrochloric acid?
Potassium reacts explosively.
Why use potassium dichromate in uv calibration?
Because Potasium dichromate (Potassium Dichromate solvated in dilute (0.001N) perchlorate acid) gives absorption at two characteristics wavelength at 235nm to 350nm ( for 20mg/L to 100mg/L) and 430nm (for 600mg/L) that's why used in wide range for linerity test of spectrophotometer.
What happens when you mix potassium and dilute hydrochloric acid should you dp it in school laboratories?
it makes a masive explosion

Why we add conc sulphuric acid in mohr salt in the titration of mohr salt against potassium dichromate?
For preparation of standard solution of Mohr salt {FeSO4.(NH4)2SO4.6H2O}, it's necessary to add dilute H2SO4 to prevent the Fe2+ ions of Mohr salt solution from undergoing oxidation (to Fe3+).
Why is the reaction between potassium and dilute acid not used to laboratory?
The reaction between potassium and a dilute acid or even just water (which is what an acid is diluted in) is very dangerous. On contact with the acid the potassium bursts into flame and may even explode, sending flaming molten pieces of potassium into the air.
A dilute aqueous potassium nitrate solution is best classified as a?
