Question

What is the total ionic and net ionic equation for this aqueous reaction?:

Sr(OH)2(aq) + HClO2 (aq)

-I wrote the molecular as:
Sr(OH)2 (aq) + HClO2 (aq) ---> SrClO2 (aq) + H20 (l)

-Is the Total Ionic:
Sr2+ (aq) + 2OH- (aq) + H+ (aq) + 2ClO- (aq) ---> Sr2+ (aq) + 2ClO-(aq) + H2O (l)

Answer 1

The molecular should be written:
Sr(OH)2 (aq) + HClO2 (aq) --> Sr(ClO2)2 (aq) + 2H2O (l)

The complete ionic equation would then be:
Sr2+ (aq) + 2OH- (aq) + 2H+ (aq) + 2ClO2-(aq) --> Sr2+ (aq) + 2OH- (aq) + 2ClO2-(aq) + 2H2O (l)

You were close but chlorite ion is ClO2- instead of 2ClO- and since strontium has a 2+ charge, there would have to be two chlorite ions.

Also the net ionic equation is 2OH- (aq) + 2H+ (aq) --> 2H2O (l)

I hope this helps!

If you need any further help, khan academy has some good article. Just look up "complete and net ionic equations".
