Ion Reaction Equation of NaOH (Less)+Ca (HCO3)2(More)
If there is less quantity in the ion equation writing, it shall be disassembled and written according to the composition:
OH -+ Ca2++ HCO3-= CaCO3↓+ H2O
If Ca (HCO3)2(less):
2OH-+Ca2++2HCO3-=CaCO3↓+2H2O+CO32-
If there is less quantity in the ion equation, it shall be disassembled and written according to the composition:
OH -+ Ca2++ HCO3-= CaCO3↓+ H2O
If Ca (HCO3)2(less):
2OH-+Ca2++2HCO3-=CaCO3↓+2H2O+CO32-
Add a small and excessive amount of Ca (HCO3)2 solution to the NaOH solution. A small amount and an excessive amount of Ca (HCO3)2 solution were added to the NaOH solution. Ca (HCO3)2 Amount: Ca (HCO3)2 excess: Write the sum ion equation Add a small amount and an excess of Ca (HCO3)2 solution to the NaOH solution. A small amount and an excessive amount of Ca (HCO3)2 solution were added to the NaOH solution. Ca (HCO3)2 Low: Ca (HCO3)2 excess: Write the sum ion equation
Low amount of Ca (HCO3)2: chemical equation: Ca (HCO3)2+2NaOH=CaCO3 Na2CO3+2H2O ion equation: Ca2+2HCO3-+2OH-=CaCO3 CO32-+2H2O
Excess Ca (HCO3)2: Chemical equation: Ca (HCO3)2+NaOH=CaCO3 NaHCO3+H2O ion equation: Ca2+HCO3-+OH-=CaCO3 H2O
