Net ionic equation
« on: October 26, 2016, 06:57:39 PM »
Hello,
This is my first time finding the net ionic equation of a double replacement reaction. I just wanted to see if I did it correctly.

Double replacement reaction question

Given
Na2(CO3)Ca(OH)2 -->

Solved
Na2(CO3) + Ca(OH)2 --> Na(OH) + 2Ca(CO3)

Net Ionic Equation
CO3+Ca(OH)2----> OH+2Ca+2CO3

Spectator ions
Na---> Na

a, b - wrong
Moreover correct formulas are:
Na2CO3 and CaCO3

You write down Na2(CO3) and Ca(CO3) - this make some difference.

c- almost correct - spectator ion is on both side of equation then Na+ is sufficent
a- wrong coefficient
b- anion with + charge?, Ca(OH)2 in solution is ionic, CaCO3 is insoluble in water then we write it as if  non-ionic.

NaOH should be also without brackets
