Oxidation of alcohol

Because H2SO4 is a strong acid and so you want to minimise the level of hazard. That's the only reason I can think of but good question though

I heard that it is something to do with the heating though? No?

What's the boiling point of conc. sulfuric acid?

337 °C according to Google, but I don't know what difference there is between concentrated acid and dilute acid...

Thanks

Dilute will be in water.

Sulfuric acid starts to decompose at around 300 Celsius.

So the reagents need to be aqueous and since the concentrated acid is not aqueous, dilute acid is used instead?

Sulfuric acid starts to decompose at around 300 Celsius - > what does this suggest as the reaction is heated under reflux regardless of whether the acid is dilute or not...

Thanks

What temperature will the dilute acid boil at?

Not sure, but google said the the more dilute it is, the closer it is to 100 degrees. The more concentrated the acid, the higher the boiling point. But I am very lost now.

So dilute boils at about 100 degrees and concentrated at 337 degrees.

Sulfuric acid starts decomposition at 300 degrees.

Which of dilute and concentrated do you therefore not want to reflux?

So dilute acid is better because you don't want it to decompose. Okay

why is dilute acid the answer not concentrated acid ?

Thanks.
