Question

Write the balanced net ionic equation for the following:

HCl(aq)+Li2CO3(aq)→

Answer 1

Look at the molecular equation first:

Li2CO3(aq) + 2HCl(aq) ==> 2LiCl(sq) + H2CO3(aq) ==> 2LiCl(aq) + CO2(g) + H2O(l)

From this, we can write the total ionic equation:

2Li+(aq) + CO32-(aq) + 2H+(aq) + 2Cl-(aq) ==> 2Li+(aq) + 2Cl-(aq) + CO2(g) + H2O(l)

Now we cancel the spectator ions and we are left with the net ionic equation:

CO32-(aq) + 2H+(aq) ==> CO2(g) + H2O(l)
