When I googled how to balance this chemical equation K2CrO4+NaHSO3+H2O=NaHSO4+KOH+Cr(OH)3 they gave me the balanced form of 2K2CrO4+3NaHSO3+5H2O=3NaHSO4+4KOH+2Cr(OH)3. But I don't know how to get this because to me it would seem unbalanced.
whatever is on one side of the equation needs to be the same as the other. So K2CrO4+NaHSO3+H2O=NaHSO4+KOH+Cr(OH)3 you need to balance the equation between the = to make a balanced equation.
