Question

equivalent weight of 2kmno4+2koh gives 2k2mno4+h2o+o in alkaline medium

Answer 1

Answer:

equivalent weight of kmno4 is 158

Explanation:

the equivalent weight of kmno4 in alkali medium is

weight of kmno4 is 158 gms

mno4- is coverted into  mno42- carries from +7 to +6

therefore n=1

equivalent weight=molecular wt/n factor

                              =158/1

                                =158
