Primarygun Posted September 5, 2004 Share 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 Share Posted September 5, 2004 it should be NaOH --H2O--> Na+ + OH- all reactions involve heat changes Link to comment Share on other sites More sharing options...
Primarygun Posted September 5, 2004 Author Share Posted September 5, 2004 it should be NaOH --H2O--> Na+ + OH- Not this ?NaOH+H2O---->Na+ +OH- + H2O Link to comment Share on other sites More sharing options...
budullewraagh Posted September 5, 2004 Share Posted September 5, 2004 no. the H2O is only relevant because it is what causes the decomposition Link to comment Share on other sites More sharing options...
Primarygun Posted September 6, 2004 Author Share 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. Link to comment Share on other sites More sharing options...
budullewraagh Posted September 6, 2004 Share Posted September 6, 2004 things tend to not react with water, per se. if there is an "ionic" bond, it should dissociate. Link to comment Share on other sites More sharing options...
