Question

HNO3 + Ba(OH)2 molecular ,ionic and net ionic equation

Answer 1

Molecular:

2HNO3 + Ba(OH)2 --> Ba(NO3)2 + 2H2O

Ionic: you need to know the solubility phases of all compounds for this step

2HNO3(aq) + Ba(OH)2(s) --> Ba(NO3)2(aq)+ 2H2O(l)

Only separate aqueous (aq)

2H+ + 2NO3- + Ba(OH)2(s) --> Ba 2+ + 2NO3- + 2H2O(l)

Net ionic: eliminate all compounds that are the same on both sides (2NO3-)

You are left with

2H+ + Ba(OH)2(s) --> Ba2+ + 2H2O(l)
