XeO3 + I- ----> Xe + I2 (acidic solution) CN)2 -----> CN- + OCN- (basic solution) MnO2 + SO32- ---> Mn2+ + S2O62- (acidic solution) H2SeO3 + H2S -----> S + Se (acidic solution) Cl2 ---> Cl- + ClO3- (basic solution) ClNO2 -----> NO3- + Cl- (acidic solution)
Balance the following equation for a basic solution. MnO4-+C2O4-2= Mno2 + CO3-2
