How is net ionic equation written from a complete ionic equation?

Answer 1

the spectator ions are removed

Answer 2

A Net Ionic Equation is a chemical equation for a reaction which lists only those species participating in the reaction.

To write a Net Ionic Reaction, follow these 3 steps:

1) Start by simply writing the overall balanced chemical reaction. This is also called the Molecular Equation.

2) Then, you break apart the soluble molecules into the two ions that are formed (one positive and one negative). You will have to use the solubility rules to do this, they can be found online. If something is insoluble, it should not be broken apart. Write the reaction out with all of the separated ions. This is called the Total Ionic Equation.

3) Then, you simplify by canceling things out if they appear on both sides of the reaction, resulting in the Net Ionic Equation.

or write one reduction half

and other oxidation half and simply add them

For example, let look at the reaction of calcium carbonate with hydrochloric acid to form calcium chloride, water, and carbon dioxide:

--Molecular Equation:

CaCO3(s) + 2HCl(aq) ---> CaCl2(aq) + H2O(l) + CO2(g)

--Total Ionic Equation:

CaCO3(s) + 2H+(aq) + 2Cl-(aq) ---> Ca2+(aq) + 2Cl-(aq) + H2O(l) + CO2(g)

--Net Ionic Equation:

CaCO3(s) + 2H+(aq) ---> Ca2+(aq) + H2O(l) + CO2(g)

Notice that the Cl- was canceled out from the Net Ionic Equation, because it really isn't playing an important part of this reaction. It is just there to balance out the charge because you can't have an ion just by itself -- you must always pair an ion with another one of opposite charge so that the overall charge is zero.

Answer 3

it must be cleared that while writing a chemical equation... it must be in symbols of that element

then the numbers of the atoms used in the reaction must be equated to both the sides that is it must be equal to right hand side as well as left hand side... we need to remember the symbols of that element

Answer 4

To write the net ionic equation from a complete ionic equation, eliminate the spectator ions that appear on both sides of the equation. The remaining ions are used to form the net ionic equation, which shows only the ions that participate in the reaction.

Answer 5

By removing from the complete equation any ions that occur in the same number on both sides of the complete equation.

Answer 6

reactants----> products
