Arrhenious Bases
« on: April 08, 2005, 01:04:33 AM »
I don't completely understand everything that goes on when an acid ionizes in a solution.  (With Arrhenious bases, the textbook says they "dissociate" in solution to release hydroxide ions into the solution. )
For instance,
b. NH3 as Arrhenious base
NH3 + H20 yields NH4 + OH

a. Ionization of HClO3 in water
I would think that it would react with water and remove a hydrogen, leaving OH- but the equation is HClO3 + H2O yields H3O+ + ClO3-.

I don't understand like... how to know when OH is going to form and when it isn't; are Arrhenious bases when the easiest products to form involve OH?

water is amphoteric in behave like acid when react with behave like base while reacting with presence of NH3 it donates H+ to NH3 solution because NH3 is lewis base.But HClO3 is very strong dissociates to give H+ ion to water.hence H3O+ is formed.for this second reaction water behaves like as a base.
