Question

From the balanced molecular equations and total ionic equation, determine the net ionic equations for the following reactions. Report only the net ionic equation in the following format: H^+1(aq) + OH^-1(aq) -> H2O(l)

K2CO3(aq) + Ba(OH)2(aq) ⟶ 2KOH(aq) + BaCO3(s)

Answer 1

molecular equation is:

K2CO3 (aq) + Ba(OH)2 (aq) --> 2 KOH (aq) + BaCO3 (s)

To get complete ionic equation, break aqueous components into respective ions

So, the complete ionic equation is

2 K+ (aq) + CO32- (aq) + Ba2+ (aq) + 2 OH- (aq) --> 2 K+ (aq) + 2 OH- (aq) + BaCO3 (s)

To get net ionic equation, remove the common ions from both sides

So, the net ionic equation is

Ba2+ (aq) + CO32- (aq) --> BaCO3 (s)

Ba^2+ (aq) + CO3^2- (aq) --> BaCO3 (s)
