When concentrated aqueous solutions of #Ba(OH)_2# and #Li_2SO_4# are mixed, a precipitate forms. How do you write balanced molecular, total ionic, and net ionic equations for this chemical reaction?

Answer:

#"Barium hydroxide + lithium sulfate "rarr" barium sulfate + lithium hydroxide"#

Explanation:

#Ba(OH)_2(aq) + Li_2SO_4(aq) rarr BaSO_4(s)darr + Li(OH)_2(aq)#

#Ba^(2+) + cancel(2HO^(-)) + cancel(2Li^+) + SO_4^(2-) rarr BaSO_4(s)darr +cancel(2Li^+) + cancel(2HO^(-))#

And net, because hydroxide and lithium ions are simply along for the ride:

#Ba^(2+) + SO_4^(2-) rarr BaSO_4(s)darr #

Is mass conserved? Is charge conserved in each equation? If not, they should be!
