Use a net lonic equation to Justify your answer. Include physical states in your answer. 2+ 2- Ba (aq)+ SO (aq)BaSO4(s) Edit Question Attempts: 1

Explanation / Answer

Note that ions in solution will start decreasing

since BaSO4(s) is forming, which implies Ba+2 and SO4-2 dissapear

so

the electricla conductivity will decrease regularly.... until

molecular

Ba(OH)2(aq) + H2SO4(aq) --> 2H2O(l) + Ba2SO4(s)

ionic

Ba+2(aq) + 2OH-(aq) + 2H+(aq) + SO4-2(aq) --> 2H2O(l) + Ba2SO4(s)

net ionic:

get rid of spectator ions = none

Ba+2(aq) + 2OH-(aq) + 2H+(aq) + SO4-2(aq) --> 2H2O(l) + Ba2SO4(s)
