I have to write a net ionic equation for nitric acid and calcium hydroxide and all the answers I’ve submitted have been rejected. If someone could explain how to create the equation that would be great.
Write your reactants as ions in solution, as well as your products as either ions or molecules. Then cancel out things that appear on either side of the reaction
So:
2HNO3 + Ca(OH)2 -> Ca(NO3)2 + 2H2O
becomes
2H+(aq) + 2NO3-(aq) + Ca2+(aq) + 2OH-(aq) -> Ca2+(aq) + 2NO3-(aq) + 2H2O(l)
As you can see, 2NO3- and Ca2+ appears on both sides of the equation, so we cancel them out, and they are excluded from the net ionic equation
Net ionic:
2H+ (aq) + 2OH- (aq) - 2H2O (l)
