Do you think that washing soda, #Na_2CO_3#, could be used for the same purpose as baking soda, #NaHCO_3#? Would #Na_2CO_3# react with #HCl#? How do you write the chemical equation for the reaction of #NaHCO_3# with #HCl#?

Answer:

I would not put sodium carbonate in my cake!

Explanation:

#NaHCO_3(aq)+HCl(aq)rarrNaCl(aq) + CO_2(g)uarr+H_2O(l)#

Sodium bicarbonate is commonly used as baking powder. (The commercial reagent is a mixture of stuff, including sodium bicarbonate, and possibly some sodium carbonate, but don't quote me.)

Of course sodium carbonate would speciate the same way:

#Na_2CO_3(aq) + 2HCl(aq) rarr 2NaCl(aq) + CO_2(g)uarr + H_2O(g)#

But I suspect that the cake you baked with washing soda would taste bitter.
