Sodium Hydroxide reacts with hydrobromic acid to yield two products. Write out a balanced molecular reaction, overall ionic reaction and a net ion reaction.
I have the molecular reaction, which I got:
NaOH + HBr -> NaBr + H20
Correct?
Any help with the next two?
Yes, your balanced molecular reaction is correct:
NaOH + HBr -> NaBr + H2O
To write the overall ionic reaction, we need to break the soluble compounds into their respective ions. Sodium hydroxide (NaOH) and hydrobromic acid (HBr) are both strong electrolytes and dissociate completely in water:
NaOH -> Na+ + OH-
HBr -> H+ + Br-
Now, let's write the overall ionic reaction by combining the ions that are common to both sides of the reaction:
Na+ + OH- + H+ + Br- -> Na+ + Br- + H2O
Lastly, to write the net ionic reaction, we need to eliminate the spectator ions, which are the ions that appear unchanged on both sides of the equation. In this case, the sodium ions (Na+) and bromide ions (Br-) are spectators. The net ionic reaction only includes the ions that participate in the reaction:
OH- + H+ -> H2O
Therefore, the net ionic reaction is:
OH- + H+ -> H2O
