This also has the effect of balancing the hydrogen and the equation is now balanced as Na2CO3 2HCl - 2NaCl H2CO3. Na2CO3 HCl - 2NaCl H2CO3. A net ionic equation is derived from a balanced chemical equation so we need to have a balanced chemical equation before proceeding.
We write net ionic equations to understand what is changing in a chemical reaction.
In the above equation the overall charge is zero or neutral on both sides of the equation. Na2CO3 HCl - 2NaCl H2CO3. The key difference between balanced equation and net ionic equation is that balanced equation shows all reactions that took place in a system together whereas net ionic equation only shows the net reaction that occurred after the completion of that particular reaction. A net ionic equation is derived from a balanced chemical equation so we need to have a balanced chemical equation before proceeding.
