Re: MHT CET chemistry Last years question papers
As you need the MHT CET chemistry Last years question paper, here I am sharing the same: Amount of oxalic acid present in a solution can be determined by its titration with KMnO4solution in the presence of H2SO4. The titration gives unsatisfactory result when carried out in the presence of HCl, because HCl i. reduces permanganate to Mn2+. ii. oxidises oxalic acid to carbon dioxide and water. iii. gets oxidised by oxalic acid to chlorine. iv. furnishes H+ ions in addition to those from oxalic acid. Q. 13. Phenol, when it first reacts with concentrated sulphuric acid and then with concentrated nitric acid, gives i. p-nitrophenol ii. nitrobenzene iii. 2,4,6-trinitrobenzene iv. o-nitrophenol Remaining questions are in the attachment, download it freely from here: |
