Reaction of sugar with sulfuric acid

  Reaction of Sugar with Concentrated Sulphuric Acid :- 

At a glance:-

When concentrated sulphuric acid reacts with sugar it acts as a dehydrating agent; removing water from the sugar. 

During Experiment

 C12H22O11 (sugar) + H2SO4 (sulfuric acid) → 12 C (carbon) + 11 H2O (water) + mixture of water and acid.

 It is an extremely exothermic reaction process . And it produce  high amount of heat. 

Which elements are produced when sulfuric acid is added to sugar?

       When Concentrated sulfuric acid is mixed with household sugar, which is attacked by the acid. The final products are carbon, water vapor, and sulfur dioxide gas. 

What do you observe when concentrated Sulphuric acid is added to sugar? 

  

 Concentrated sulphuric acid is a strong dehydrating agent and it pulls the sugar molecules apart leaving just black carbon which froths due to the heat and water produced. 

What happens when sugar is burned? 
     Sugar is made of carbon, hydrogen and oxygen atoms. When heated over a candle, these elements react with the fire to turn into a liquid. The heat causes the sugar's atoms to combine with the oxygen in the air, forming new groups of atoms. Energy is released in this chemical reaction in the form of smoke and black soot.

What happens when carbon reacts with Sulphuric acid? 
  Actually  sulfuric acid should be a Concentrated and heated solution, for this reason  Carbon reacts with sulfuric acid to produce carbon dioxide and sulfur dioxide gas along with water.
