Question

write the balanced formula, complete ionic, and net ionic equations for the reactions that occur when the following are mixed: barium hydroxide (aq) and hydrochloric acid

Explanation / Answer

Ba(OH)2(s) + 2HCl(aq) --> 2H2O(aq) + BaCl2(aq) A neutralization equation is when an acid and base react to form water and a salt... this is ALWAYS true. To write the net ionic equation, break the molecules in aqueous forms into their ions and if they appear on both sides of the equation, cancel them out. Then rewrite the equation. Thus, Ba(OH)2(s) + 2HCl(aq) --> 2H2O(l) + BaCl2(aq) Ba(OH)2(s) + 2H+ + 2Cl- --> 2H2O(l) + Ba^2+ + 2Cl- Ba(OH)2(s) 2H+(aq) --> 2H2O(l) + Ba^2+(aq)
