Which of the following reactions is the net ionic equation for the acid-base reaction between H 2CO 3 and Sr(OH) 2?
A. H2CO3 + Sr2+ + 2OH− → SrCO3 + 2H2O
B. H3O+ + OH− → 2H2O
C. 2H3O+ + Sr2+ + 2OH− → Sr2+ + 4H2O
D. H2CO3 + 2OH− → 2H2O + CO32−
E. H2CO3 + Sr(OH)2 → 2H2O + Sr2+ + CO32−
Answer: H2CO3 + Sr2+ + 2OH− → SrCO3 + 2H2O
