Primarygun Posted September 5, 2004 Posted September 5, 2004 Do chemistry books always simplify the equation as net ionic equation in solution area? Such as NaOH+H2O---->Na+ +OH- + H2O it simplifies as NaOH--->Na++OH It is in contrast as HCl, and it makes me confused for a while. By the way, is all reaction involved heat ?
budullewraagh Posted September 5, 2004 Posted September 5, 2004 it should be NaOH --H2O--> Na+ + OH- all reactions involve heat changes
Primarygun Posted September 5, 2004 Author Posted September 5, 2004 it should be NaOH --H2O--> Na+ + OH- Not this ?NaOH+H2O---->Na+ +OH- + H2O
budullewraagh Posted September 5, 2004 Posted September 5, 2004 no. the H2O is only relevant because it is what causes the decomposition
Primarygun Posted September 6, 2004 Author Posted September 6, 2004 How can you determine whether the reactants goes displacement or not? Can you teach me some skills? Such as NaCl(s)+H2O(l)--->NaCl(aq) instead of reacting.
budullewraagh Posted September 6, 2004 Posted September 6, 2004 things tend to not react with water, per se. if there is an "ionic" bond, it should dissociate.
