Title: full and ionic eqns.
Post by: mandy on September 01, 2009, 10:00:26 pm: How do I find the ionic eqns of these:

HNO₃ (aq) + KOH -----> H₂O (l) + KNO₃ (aq)

and

2HCl (aq) + Na₂CO₃ (aq) ------> H₂O (l) + CO₂ (g) + 2NaCl (aq)

For the first one you can see that NO3 is in (aq) on both sides
so you'd get rid of it

therefore

$H^+ (aq) + KOH (aq) \implies H_2O (l) + K^+ (aq)$
