The solution gets hot
Nothing.
Concentrated sulfuric acid strips the hydrogen and oxygen from sugar (sucrose) as water. Carbon is left. C12H22O11 + H2SO4 --> 12C + H2SO4. 11H2O
nothing happens
The most fizzing will come from the concentrated sulfuric acid, then dilute sulfuric acid, then the acetic acid.The amount of fizzing is due to the concentration of H+ in the solution, and concentrated sulfuric acid has the most H+ in solution. The dilute sulfuric acid has less (because it is dilute) and the acetic acid solution has the least of all because it is a weak acid rather than a strong acid.See the Related Questions for more information.
If it is added to a solution of dilute sulfuric acid, it will react slowly liberating hydrogen gas. With concentrated acid, iron will undergo a series of red-ox reactions.
copper sulphate and hydrogen is released.

MgSO4+ H2O + CO2
zinc sulfate is formed H2 gas is evolved
Pb2+ --> PbSO4(s)Concentrated sulfuric acid will 'burn' or 'carbon'ise acetate (CH3COO-) to Carbon black, CO2(g) and H2O(l) and some other intermediate products.Be very carefull! Very exothermic!You should never work with concentrated acids un-gided and unprotected!.
U evaporate it
The (N) stands for Normal. 1 Normal is 28 ml of concentrated sulfuric acid added to deionized water for a final volume of 1 Liter (L). 18 N is roughly a 50 percent concentration sulfuric acid.
