Question

Fe2+ + cr2o72- = fe3+ + cr3+ how do i balance this reaction in acidic solution?

Answer 1

Explanation:

if it is useful mark it as brainliest answer

Answer 2

Answer:

dichromate is the oxidising agent

6Fe2+ + Cr2o7^2- + 14H+ → 6Fe3+  +2Cr3+  + 7H2O

Explanation:

we use the technique  of 1/2 of -equations

Reduction 1/2 of equations:-

Cr2o7^2- + 14H+ +6e- → 2Cr3+ + 7H2O

Oxidation Half reaction:-

Fe2+ →Fe3+ +e-

and we upload the equations collectively  withinside the quick of way the sort of manner that the electrons are eliminated..

6Fe2+ + Cr2o7^2- + 14H+ → 6Fe3+  +2Cr3+  + 7H2O
