你好，我认为这里讲的是净离子方程式。我给你举个例子吧，比如酸碱反应。我有一个盐酸HCl，和氢氧化钠NaOH.那么化学反应式为HCl+NaOH=NaCl+H2O
In the net ionic equation, all species with (s), (l), and (g) will be unchanged. Any (aq) that remain on both sides of the equation (reactants and products) can be canceled out. These are called "spectator ions" and they don't participate in the reaction. Tips for Writing the ...
An example of a net ionic equation is the net reaction for 2AgNO3 + BaCl2 --> Ba(NO3)2 + 2AgCl. The precipitate is AgCl, so the net ionic equation shows the synthesis of AgCl: Ag+ (aq) + Cl- (aq) --> AgCl(s). How are net ionic equations written?
For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. Compound states [like (s) (aq) or (g)] are not required. You can use parenthesis () or brackets [].
Example 1: Lead acetate and copper sulfate solutions are mixed: Pb(C2H3O2)2 (aq) + CuSO4 (aq) PbSO4(s) + Cu(C2H3O2)2 (aq) Complete ionic equation: Pb+2(aq) + 2 C2H3O2-(aq) + Cu+2(aq) + SO4-2(aq) PbSO4(s) + Cu+2(aq) + 2 C2H3O2-(aq) Notice that insoluble...
Precipitation Reactions Let's first start with a complete chemical equation and see how the net ionic equation is de- rived. For example, take the reaction of lead(II) nitrate with hydrochloric acid to form lead(II) chloride and nitric acid, shown below: Pb(NO 3 ) 2 (aq) + 2 HCl ...
