It slowly absorbs moisture (water molecules) from air and becomes diluted with the passage of time.
Concentrated sulfuric acid strips the hydrogen and oxygen from sugar (sucrose) as water. Carbon is left. C12H22O11 + H2SO4 --> 12C + H2SO4. 11H2O
Driving off the water from dilute sulfuric acid will increase the concentration of the acid to the point where it will contain virtually no water.
Concentrated sulfuric acid is stronger and more acidic than an equal concentration of acetic acid.Sulfuric acid is considered a strong acid because it dissociates completely in water, whereas acetic acid is considered a weak acid because it does not dissociate completely in water.See the Related Questions link to the left for more information about strong and weak acids.
sulphuric acid can be upto 78% concentrated >>>> Typically, "concentrated" acid can be upto around 98%. It can be taken to 100% however will fume and absorb water from the atmosphere if it can until it reaches around 98% again. Nitric acid is much lower - conc is usually just under 70% - beyond that it give off reddish gold gas (nitrogen dioxide) which is incredibly caustic to inhale (causes death by drowning upto two days later as the lungs dissolve and fill with fluid. Reason being nitrogen dioxide and water convert to concentrated nitric acid) Hydrochloric acid is lower still - around 33-35% beyond that it will fume of hydrogen chloride gas until the concentration reverts to around 33-35%. Unlike the other two acids mentioned above, hydrochloric will eventually evaporate away without trace - so is used for cleaning things like swimming pool surroundings - as once it has dried, there is no acid left.
Sulfuric acid is commonly used in the textile industry for processes such as dyeing and printing of fabrics. It helps in setting the dyes on the fabric and improving color fastness. Sulfuric acid also helps in modifying the pH levels of the solutions used in textile processing.

Yes. Add concentrated sulfuric acid which is a dehydrating agent. It will form a black foamy mass. Rinse with water and filter and rinse again. Dry in an oven and carbon will be left.

A couple of definitions of acids:1. a substance which forms H+ ions in solution2. a proton donor some chemical formulas for acids- H2SO4 sulfuric acid- HCl hydrochloric acid- HNO3 nitric acidSee the Related Questions to the left for more information and other examples.
If the sulfuric acid is left out of the reaction, the acetylsalicylic acid synthesis may proceed at a slower rate or not to completion. The presence of sulfuric acid helps catalyze the reaction and improves the yield of acetylsalicylic acid. It also helps in the dehydration of acetic acid formed during the reaction.
The equation for the reaction is: H{2}SO{4} + 2NH{3} → (NH{4}){2}SO{4} [Numbers in braces are supposed to be subscripts, but I can't do them here.] This says that 1 mole of sulphuric acid reacts with 2 moles of nitrogen to create 1 mole of ammonium sulphate. 1 mole of a substance weighs the same as its atomic weight in grams. 1 mole of NH{3} weighs 14 + 3 × 1 = 17 g Thus 2 × 17 g = 34 g of ammonia react with 1 mole of sulphuric acid. To react with 300 g of ammonia requires 300 g ÷ 34 g/mol ≈ 8.8 moles of sulphuric acid Therefore there will be 36.0 - 8.8 = 27.2 moles of sulphuric acid left.
This reaction yields zinc sulphate and hydrogen gas.
