Question

A) Complete and balance equation: CH3COOH(aq)+ Sr(OH)2(aq)------>______________________ B) Write net ionic equation (include states):________________

Explanation / Answer

irst you must write a properly balanced molecular equation. 1. 2CH2COOH(aq) + Sr(OH)2(aq) --> Sr(CH3COO)2(aq) + 2H2O(l) Correct this to: 2 CH3COOH(aq) + Sr(OH)2(aq) = Sr(CH3COO)2(aq) + 2 H2O(l) Now write this in ionic form, to give a full ionic equation: Remember that only compounds that are (aq) can be dissociated. Anything that is (s) (g) or (l) cannot be shown as dissociating to ions. Full ionic equation: 2CH3COO- (aq) + 2H+(aq) + Sr 2+(aq) + 2OH-(aq) ? 2CH3COO- (aq) + Sr 2+(aq) +2H2O(l) Now check for anything which is identical on both sides of the equation. Cancel these out to give the net ionic equation: The common are: 2CH3COO- (aq) + Sr 2+(aq) . Cancel these out. Net ionic equation - what is left: 2H+(aq) + 2OH-(aq) ? 2H2O (l)
