A:\:The number of moles KMnO_{4 } that will be needed to react with 1 – InterviewSolution

1.	A:\:The number of moles KMnO_{4 } that will be needed to react with 1 mole of HCN ( while HCN oxidises into CO_3^{2-} and NO_3^- ) in acidic medium is 0.5 . R : Because the n-factor of KMnO_4 in acidic medium is 5 and the n-factor of HCN is 10 . So, molar ratio of KMnO_4 to HCN is 1:2.
