    Need some help:

    With determining the ratio of HCl to NaHCO3

    NaOH + HCl -> NaCl + H2O

    Na2CO3 + HCl -> NaHCO3 + NaCl

    Is the ratio 2:1 of HCl to NaHCO3 or 1:1?

    If the equation is balanced, it is 1:1 (as shown). The 1 & 1 come from the big numbers in front of the formulae in the equation.
