Question

Write the complete ionic and the net ionic equations.
BaCl2(aq)+2NaIO3(aq)➡Ba(IO3)2(aq)+2NaCl (aq)
2NaOH(aq)+BaCl2(aq)➡Ba(OH)2(s)+2NaCl(aq)

Answer 1

1) BaCl2(aq)+2NaIO3(aq)-------------------->Ba(IO3)2(aq)+2NaCl (aq)

complete ionic :

Ba+2 (aq) + 2 Cl- (aq) + 2 Na+ (aq) + 2 IO3- (aq) ---------------> Ba+2 (aq) + 2IO3- (aq) + 2Na+ (aq) + 2 Cl- (aq)

there is no net ionic eqaution this takes place becuase it is just ions displacement

so complete ionic is net ionic

2) 2NaOH(aq)+BaCl2(aq)➡Ba(OH)2(s)+2NaCl(aq)

complete ionic
2Na+ (aq) + 2OH- (aq) + Ba+2 (aq) + 2Cl- (aq) ---------------> Ba(OH)2 (s) + 2 Na+ (aq) + 2Cl- (aq)

net ionic :

Ba+2 (aq) + 2OH- (aq) ----------------> Ba(OH)2 (s)
