What is the net ionic equation for calcuim ion and ammonium oxalate?
Look for a precipitate, a gas, or a weak electrolyte. In this case, CaC2O4 is insoluble. Here is a simplified list of the solubility rules.

Ca^+2(aq) + C2O4^-2(aq) ==> CaC2O4(s)
To determine the net ionic equation for the reaction between calcium ions (Ca2+) and ammonium oxalate (NH4)2C2O4, you need to first understand the chemical formulas of the compounds involved.
Calcium ion is represented by Ca2+, indicating its charge of +2. Ammonium oxalate is composed of the ammonium ion (NH4+) and the oxalate ion (C2O42-).
Now, let's find the complete ionic equation by dissociating the compounds that are soluble and remain as ions in solution. However, it's essential to recognize that calcium oxalate is generally insoluble.
The complete ionic equation can be written as follows:
Ca2+(aq) + (NH4)2C2O4(aq) → CaC2O4(s) + 2NH4+(aq)
Here, (aq) denotes that the ion is dissolved in the aqueous solution, and (s) represents the formation of a solid precipitate.
To obtain the net ionic equation, you will need to eliminate any spectator ions, which are ions that appear on both sides of the equation and do not participate in the actual chemical reaction.
In this case, the ammonium ion (NH4+) appears on both sides of the reaction, so it is a spectator ion and can be removed from the equation.
The resulting net ionic equation is:
Ca2+(aq) + C2O42-(aq) → CaC2O4(s)
This equation more clearly represents the chemical reaction between calcium ions and ammonium oxalate, showing the formation of a solid precipitate known as calcium oxalate.
