`KMnO_4+H_2 SO_4+NaHSO_3` 

`4KMnO4+H_2SO_4+10NaHSO_3 = 4MnSO_4+2K_2SO_4+ 5Na_2SO_4+6 H_2O` 

`KMnO_4+NaOH+NaHSO_3`

`2KMnO_4+3NaOH+NaHSO_3 = K_2SO_4+2Na_2MnO_4+2H_2O`  

`KMnO_4+NaHSO_3`

`KMnO_4 + NaHSO_3 = KHSO_3 + NaMnO_4`

`OR`

`KMnO_4 + NaHSO_3 = H_2O + K_2SO_4 + MnO_2 + Na_2SO_4 + NaHSO_4`

`OR`

`KMnO_4 + NaHSO_3 = H_2O + H_2SO_4 + K_2SO_4 + MnO_2 + Na_2SO_4`

You need to balance the equation `KMnO_4 + H_2SO_4 + NaHSO_3 = MnSO_4 + K_2SO_4 + Na_2SO_4 + H_2O` , such that:

`4KMnO4 + H_2SO_4 + 10 NaHSO_3 = 4MnSO_4+2K_2SO_4 + 5Na_2SO_4 + 6H_2O`

You need to balance the following equation, `KMnO_4 + NaOH + NaHSO_3 = K_2SO_4 + Na_2MnO_4 + H_2O` , such that:

`2KMnO_4 + 3NaOH + NaHSO_3 = K2SO4 + 2Na_2MnO4 + 2H_2O`

You need to balance the following equation, `KMnO_4+NaHSO_3= KHSO_3 + NaMnO_4` , such that:

`KMnO_4+NaHSO_3 = KHSO_3 + NaMnO_4`

`2KMnO_4 + 3NaHSO_3 = H_2O + K_2SO_4 + 2MnO_2 + Na_2SO_4 + NaHSO_4`

`4KMnO_4 + 6NaHSO_3 = 2H_2O + H_2SO_4 + 2K_2SO_4 +4 MnO_2 + 3Na_2SO_4`
