Question

As plain and simple as possible i need to know how to find a net ionic equation????? Any example will do. This concept is not clicking in my head.

Answer 1

well, try this
http://chemistry.about.com/library/glossary/bldef57220.htm

in order to figure it out, u need to know which of your components actually stay in the solutions as ions (so they do not take part in your net ion equation) and which ones do not. the ones that do nor are 3 categories. they are either solid, i.e. insoluble in water, gases, or weak electrolytes (i.e. do not dissociate directly and completely into ions-a perfect example are most organic acids, or generally weak acids and bases)

Answer 2

The net ionic equation is what happens between the ions that make the reaction go. Other ions are sometimes called "bystander ions." For example:

Write the net ionic equation for AgNO3(aq) + NaCl(aq) ===> AgCl(s) + NaNO3(aq)
Answer: Ag+ + Cl- ===> AgCl
Precipitation of AgCl is what makes it all go.

Write the net ionic reaction for NaHCO3(aq) + HCl(aq) ===> NaCl(aq) + CO2(g) + H2O
Answer: HCO3- + H+ ===> CO2 + H2O
That's a little tricky, because CO2 and H2O aren't themselves ions.

I gave equations in the examples. Sometimes the questions are expressed in words--the names of the compounds.

Answer 3

a net ionic equation shows the net charges off all of the ions in the ionic compounds
i.e. Na(+)Cl(-1) + H2(+2)SO4(-2)------->H(+1)Cl (-1) + Na(+1) HSO4(-1)

the numbers in parenthesies should be superscript representing oxidation state.
