Question

Balance the equation in aqueous acidic solution:
IO-(aq) + I-(aq) → I2(s)

i know you have to add either water or H+ but i cant seem to balance it out

thanks for the help!!

Answer 1

2H+ + IO- + I- >>I2 + H2O

Answer 2

thanks!..for a basic solution would you just add OH then?
for example:
Mn2+(aq) + ClO3-(aq) → MnO2(s) + ClO2(g)
