wasnt the colour change from orange to green?I said the colour change was from colourless to pale pink . I wrote colorimetry aswell
For error thing it was 0.x something. For the nmr they said there were 6 peaks
Solvent extraction
i said open the tap to allow the two layers to separate, didn't specify which one and then again put the separated into a separating funnel and add Sodium carbonate... Not sure about this one though
Do you think our answers are correct ? It makes sense as there will be no splitting on CH3 group
I didn't show the OH because they only wanted you to the side chain

So, is the colour change from purple to pink or colourless to pink?The agent used was KMnO4, not K2Cr2O7
Purple to colourlessSo, is the colour change from purple to pink or colourless to pink?
Isn't Mn2+ pink in colour?Purple to colourless
In acid, it become colourless. After the first permanent pale pink colour, the final colour change is colourless.Isn't Mn2+ pink in colour?
It stays pink until excess solution added, something like that.What does "permanent" means I wonder -__- Please forgive my unyielding... I would like to make it clear before my Unit 4 and 5 exam ~
