Question

Magnesium hydroxide is insoluble in pure water but will react with a hydrochloric acid solution as in the equation below. Which choice represents the correct ionic and net ionic equation for the reaction?

Mg(OH)2(s)  +  2HCl(aq) -->  MgCl2(aq)  +  2 H2O(l)

Select one:
a. ionic:  Mg(OH)2  +  2H+  +  2Cl-  -->  Mg2+  +  2 Cl-  +  2H2O
net:     Mg(OH)2   + 2 H+  -->  2H2O  +  Mg2+
b. ionic:  Mg2+  +  2 OH-  +  2H+  +  2Cl-  -->  Mg2+  +  2 Cl-  +  2H+  + 2OH-

net:     Mg2+  +  2 OH-  +  2H+  +  2Cl- -->  MgCl2   +  2H2O
c. ionic:  Mg2+  +  2 O2- + 4H+  +  2Cl-  -->  Mg2+  +  2 Cl-  +  2H2O
net:     2O2-  + 4 H+  -->  2H2O
d. ionic:  Mg2+  +  2 OH-  +  2H+  +  2Cl-  -->  Mg2+  +  2 Cl-  +  2H2O
net:     2OH-  + 2 H+  -->  2H2O
