How to write the ion equation of excess Ca (HCO3)2 solution with NaOH solution?
Since Ca (HCO3)2 is excessive, HCO3- can not be completely reacted. The chemical equation is:
Ca (HCO3)2+NaOH=CaCO3 NaHCO3+H2O
The ion equation is: Ca^2++HCO3-+OH^-==CaCO3 H2O
Drop a small amount of NaOH solution into the excess Ca (HCO3)2 solution to the reaction ion equation
Ca2+OH-+HCO3-=CaCO3 precipitation+H2O
