For the chemical reaction HCN ( aq ) + KOH ( aq ) ⟶ H 2 O ( l ) + KCN ( aq ) HCN(aq)+KOH(aq)⟶H2O(l)+KCN(aq) write the net ionic equation, including the phases. net ionic equation:

H+(aq)   + OH-(aq) ⟶H2O(l)

Explanation:

Step 1: The balanced equation

HCN(aq) + KOH(aq) ⟶ H2O (l) + KCN (aq)

H+(aq) + CN-(aq) + K+(aq) + OH-(aq) ⟶H2O(l) + K+(aq) + CN-(aq)

Step 2: The net ionic equation

The net ionic equation, for which spectator ions are omitted - remember that spectator ions are those ions located on both sides of the equation - will , after canceling those spectator ions in both side, look like this:

H+(aq)   + OH-(aq) ⟶H2O(l)

oh it is true if thats what you are asking

the correct answer is:

a. formation of precipitation
