What happen when ethanol is heated with alkaline kmno4 solution?

∙ 11y ago
When ethanol is added to alkaline KMno4 solution, the ethanol gets oxidised to ethanoic acid due to nascent oxygen. KMno4 is an oxidising agent. thus when we first add alkaline Kmno4 to ethanol, the pink colour of the Kmno4 vanishes, as it is being used up for the oxidation process. however. when all of the ethanol has been oxidised into ethanoic acid, and we keep adding Kmno4, the colour returns, as there is no more ethanol left to oxidise.

What happen when ethanol is heated with bleaching powder and water?
chloroform(CHCl3) and calcium formate[(HOOC)2Ca] is formed
What will happen if a solution of sodium hydrogen carbonate heated?
Sodium carbonate would be deposited at the bottom of the solution.
Why the ethanol heated in a water bath instead of being heated directly?
Because it is inflammable
Why water bath must be used while heating ethanol and acetone?
A water bath must be used while heating ethanol and acetone because the temperatures at which they can be heated might break the container they are heated in. Some metals are also heated this way.
What will happen when a salt solution has cooled down?
nothing unless you heated it and it starts to evaporate and cause the salt to stick to the side

What would happen if an aqueous solution of sugar is heated to dryness?
Crystals of sugar are obtained.

How to produce gelatin hydrolysate?
Hydrolysis is the decomposition of materials in water and usually involves strong acid or alkaline pH. In the case of gelatin (which is a protein) it is hydrolysed in alkaline solution with heat, so something like a few grams per litre of caustic soda will make a solution which decomposes gelatin when heated. The solution of decomposed gelatin is referred to as gelatin hydrolysate.
Does it take longer to saturate a heated solution than a cold solution?
No, a heated solution will saturate faster.

When electric current is passed through a strong solution of brine then what will happen?
the water will be heated and electrolysed to give hydrogen and oxygen gases
What is the flashpoint of ethanol?
An ethanol-water solution that contains 40% ABV (alcohol by volume) will catch fire if heated to about 26 °C (79 °F) and if an ignition source is applied to it. This is called its flash point. The flash point of pure ethanol is 16.60 °C (61.88 °F), less than average room temperature.
What happens when ethanol is heated in presence of concentrated H2SO4?
ethanoic acid is formed
What happened when saturated solution is heated?
It depends on what kind of solute was mixed in a solution. for example of NaCl, it would disolved if heated.
