Hey guys! I'm after some chemistry help for my exam and will be so grateful if anyone could offer me a helping hand!!!
A) {Cr(OH)6}"-3 charge"...add hydrogen peroxide (bubbles of gas and heat produced)...................CrO4 "2-"
State & explain the following
Work out the oxidation state Of chromium in each compound.??
What happened to chromium in terms of Redox in this reaction??
B) Identifying organic solids
What would you use the following to identify?
1cm of sulphuric acid
1 cm potassium dichromate solution
*
*
*
C) Identifying organic solids
Acidified potassium dichromate changes from orange to blue green
*The dichromate ions become chromium (III) ions. Is this oxidation or reduction?
*What happens to the organic compounds in this test?
Which organic compounds containing oxygen do not react with acidified potassium dichromate? Why do they not react?
*
*
D) Identifying organic solids
Draw the skeletal formula of three possible isomers of an alcohol containing 6 carbon atoms.
This alcohol cannot be oxidised by acidified potassium dichromate
