ethanoic acid is formed
The reaction is:C + 2 H2SO4 = CO2 + 2 SO2 + 2 H2O
2,4,6-trinitrophenol
how 2.5N H2SO4 prepared from concentrated H2SO4
H2SO4 is a highly concentrated acid.
The chemical reaction (a dehydration reaction) is:C12H22O11 + H2SO4 = 12 C + 11 H2O

acetaldhyde
When reacted with concentrated H2SO4, iodine is oxidized instead of being protenated. The redox produces molecular I2 instead of acidic HI.
The first solution is more concentrated because it contains 6 moles of H2SO4 per one liter of solution. The second solution is less concentrated because it contains 0.1 moles of H2SO4 in one liter. In equal amounts of each example, the first would have more H2SO4.
to hydrolysed the trytophan
a strong acid like HF, H2SO4...are stronger when they are concentrated, weaker acids are weak even they are concentrated
