Malachite is mostly contained of Copper carbonate, which is why its green in colour. It dissolves in sulfuric acid to give Copper sulfate, Carbon dioxide and Water.
CuCO3 + H2SO4 ----> CuSO4 + H2O + CO2
Sulphuric acid is used with malachite to separate the copper and the sand. This is because the copper dissolves into the solution where as the sand remains.

When sulphur trioxide is dissolved in sulphuric acid the compound formed is oleum or fuming sulphuric acid. It is nsty stuff. !!!! However, it is part of the process inmanufacturing sulphuric acid. SO3 + H2SO4 = H2S2O7 This is then disolvedin water to make more sul[phuric acid. H2O + H2S2O7 = 2H2SO4 Notice ; we statred with one mole of H2SO4 , and the product is 2 moles of H2SO4. We have doubled to amount. NB The oleum is disolved into a large quantityt of water. NOT water is dissolbed in oleum. The reason being is if water was dissolved into oleum is would boil , and there by release fumes and particles of sulphuric acid into the environment. - Not a good idea. So the oleum is slowly dissolved intio water.

They react to form sulphuric acid. 2 SO2 + 2 H2O + O2 → 2 H2SO4

when we add water n sulphuric acid then dilute sulphuric acid is formed. But we have to mix concentrated acid to water not water to acid otherwise the container in which u r mixing may explode because this reaction is highly exothermic.
Sulphuric Acid is colourless. Water is colourless. When dissolved together, the solution remains colourless.
Copper does not react with dilute Sulphuric acid.
