Problem page write a balanced half-reaction for the reduction of solid manganese dioxide mno2 to manganese ion mn 2 in acidic aqueous solution. be sure to add physical state symbols where appropriate.

In a reduction reaction, some electrons are gained by the substance being reduced. The balanced half-reaction to this would be:

MnO2(s)  +  4 H+ (aq)  +  2e ---> Mn^2+ (aq)  +  2 H2O (aq)

It is called balanced reaction since the number of each element in the left side is equal to the number of each element on the right side.
