Net Ionic Equations are Important
The factor to write a chemistry equation is to express what we believe is actually happening in a chemical reaction.One that the most beneficial applications of the ide of primary speciesis in composing net ionic equations. These space equations that focus on the primary substances and ions connected in a reaction--the principal species--ignoring thosespectator ions that really don"t get involved. Because that example, consider the reaction described by the following full molecule equation: HCl(aq) + NaOH(aq) ![]() ![]() ![]() ![]() Writing net Ionic EquationsWriting net ionic equtaions is much easier than you might think. An initial of all, we have to start with an equation that has the physics state:(s) for solid,(l) for liquid,(g) for gas, and(aq) for aqueous solution.The 3 rules for composing net ionic equations space really rather straightforward.Only take into consideration breaking up the (aq) substances.Only rest up strong electrolytes.Delete any type of ions that appear on both sides the the equation.Clearly rule 2 is the tricky one. You must recognize your solid electrolytes: | strong acids | HCl, HBr, HI, HNO3, HClO3, HClO4, and H2SO4 | strong bases | NaOH, KOH, LiOH, Ba(OH)2, and Ca(OH)2 | salts | NaCl, KBr, MgCl2, and many, countless more, all containing steels or NH4. |
Another Example
Here"s another example: HF(aq) + AgNO3(aq)



What if i don"t have the products?
In some instances you only understand the reactants. Because that example, one can need to know the net ionc equation because that "the reaction between NaHSO4 and NH3." What then?There space two methods to proceed:Determine the "molecular equation" and also proceed as above. This works fine as lengthy as friend can number out the product in the very first place!You are watching: Naoh + hcl net ionic equation

Thus, H+ have to be transferred from the HSO4 to the NH3. HSO4(aq) + NH3(aq)
