Question

pls solve this question .its urgent .Balance this using ion electron method in basic medium​

Answer 1

Answer:

Explanation:

mno4- + s2o3-2  = mno2 + so4-2

it can be balanced by factor method

factor of mno2 = 3

factor of s2o3-2 = 4

mno4- +s2o3-2 =4mno2 + 3so4-2

4 mno4- + 3/2 s2o3-2 = 4mno2 + 3so4-2

4 mno4- +3/2 s2o3-2 = 4mno2 + 3so4-2 +1/2h2o

4 mno4- +3/2 s2o3-2 + h+ = 4 mno2 +3so4-2 + 1/2h2o

4 mno4- +3/2 s2o3 -2 = 4mno2 +3so4-2 +1/2h2o + oh-

8 mno4- +3 s2o3-2 = 8 mno2 + 6so4-2 + h2o + 2oh-
