Question

Write the balanced molecular equation for the neutralization reaction between Ba(OH)2 (a strong base) and HCl (a strong acid).
Derive the net ionic equation for that reaction.

Answer 1

i said hcl+naoh=nacl+h20

Answer 2

then net ionic is
h+oh=h2o. is that correct?

Answer 3

In neutralizations, the acid and base always creates a water and a salt.

Ba(OH)2(s) + 2HCl(aq) --> 2H2O(aq) + BaCl2(aq)

If you put these compounds in water, HCl and BaCl2 will break up because they are strong electrolytes. So the equation turns into

Ba(OH)2(s) + 2H+ + 2Cl- --> 2H2O(l) + Ba^2+ + 2Cl-

Then, you cancel out the spectator ions (things that are the same on both sides) and you get:

Ba(OH)2(s) 2H+(aq) --> 2H2O(l) + Ba^2+(aq)
