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)

Answer 2

For the given reaction ; HNO₃ + Ba(OH)₂

• Molecular reaction  = 2HNO₃ + Ba(OH)₂ ---> Ba(NO₃)₂ + 2H₂O

• Ionic reaction = 2H⁺ + 2NO₃⁻ + Ba(OH)₂(s) ---> Ba²⁺ + 2NO₃⁻ + 2H₂O(l)

• Net ionic reaction = 2H⁺ + Ba(OH)₂(s) --> Ba²⁺ + 2H₂O(l)

The molecular reaction of the the given reaction can be expressed as

Molecular reaction  = 2HNO₃ + Ba(OH)₂ ---> Ba(NO₃)₂ + 2H₂O  while

The Ionic equation of the reaction is written as

step 1 : determine the solubility phases of the compounds involved in the given reaction

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

step 2 when writing ionic equations we separate the aqueous solution int its respective ions

∴ The ionic equation becomes ;

2H⁺ + 2NO₃⁻ + Ba(OH)₂(s) ---> Ba²⁺ + 2NO₃⁻ + 2H₂O(l)

The net Ionic reaction equation is written as

Step 1 ; remove compounds found on both sides of the reaction equation.

∴ The net ionic equation becomes

2H⁺ + Ba(OH)₂(s) --> Ba²⁺ + 2H₂O(l)

Hence we can conclude that the

Molecular reaction  = 2HNO₃ + Ba(OH)₂ ---> Ba(NO₃)₂ + 2H₂O

Ionic reaction = 2H⁺ + 2NO₃⁻ + Ba(OH)₂(s) ---> Ba²⁺ + 2NO₃⁻ + 2H₂O(l)

Net ionic reaction = 2H⁺ + Ba(OH)₂(s) --> Ba²⁺ + 2H₂O(l)
