Problem: What, if any, are the spectator ions when aqueous solutions of HBr and RbOH neutralize each other? Write the full ionic and net ionic equations.

FREE Expert Solution

Step 1. Write the overall balanced reaction

Reactants:

HBr(aq) → strong acid → will break up into its ions

▪ Hbr → H+ + Br-

 RbOH(aq) → strong base → will break up into its ions

▪ RbOH → Rb+ + OH-


Products:

H+ + OH- H2O(l)

Rb+ + Br- RbBr

Cl-, Br-, and I- are soluble except when paired with Ag+, Pb2+, Cu+, Hg22+
RbBr → soluble


Overall Balanced Reaction:        

HBr(aq) + RbOH(aq) → H2O(l) + RbBr(aq)


Step 2: Write the total or full ionic equation

soluble ionic compoundsseparate and become ions in the chemical equation
compounds that are aqueous can break up into ions
insoluble compounds (solids, liquids, and gases) will not break up the solution

HBr(aq) + RbOH(aq) → H2O(l) + RbBr(aq)

▪ HBr(aq) → H+(aq) + Br-(aq)
▪ RbOH(aq) → Rb+(aq) + OH-(aq)
▪ RbBr(aq) → Rb+(aq) + Br-(aq)
