Question

Sodium hydrogen carbonate reacts with sulfuric acid to produce sodium sulfate, water, and carbon dioxide.

Write the equation out, balance, and tell what kind of reaction it is:

Answer 1

Answer:

2NaHCO3(aq)+H2SO4(aq)→Na2SO4(aq)+2CO2(g)+2H2O(l)

Explanation:

As we know that

acid + carbonate  →  salt + carbon dioxide + water

So, the general (un-balanced) equation would be-

NaHCO3(aq)+H2SO4(aq)→Na2SO4(aq)+CO2(g)+H2O(l)

Now we will write the net ionic reactions

$HCO_3^-+ H3O^+$ ----> CO2(g)↑+2H2O(l)

$Na ---> Na^+ + e^-$

$2H^+ + 2e^- ---> H2$

$SO_4^{2-} ---- SO_4 + 2e^-$

Adding all the above equation, we get

2NaHCO3(aq)+H2SO4(aq)→Na2SO4(aq)+2CO2(g)+2H2O(l)
