inshm2016 Posted July 19, 2015 Report Share Posted July 19, 2015 Hi, I am currently studying chemistry have 2 questions: 1. It says in my text book that ''acids react to form bases and vice versa''. But how is that always true? For example, a base is not formed when an acid reacts with a metal to produce a salt and hydrogen gas, right? 2. If I have understood it correctly, Kw=H+*OH- and in a neutral solution (ex. pure water), H+ = OH- and hence sqrt(Kw)=H+. Does this also mean that sqrt(Kw)=OH-? 1 Reply Link to post Share on other sites More sharing options...
kw0573 Posted July 19, 2015 Report Share Posted July 19, 2015 Hello!1)By Arrhenius and Brønsted-Lowry definitions, when an acid loses (dissociates) a proton, it is said to become a conjugate base. For example, if NH4+ (acid) loses one of its protons, it becomes NH3 (a base).In the reaction Zn(s) + 2HCl(aq) --------> ZnCl2(aq) + H2(g)The Cl-(aq) are in fact the conjugate bases to HCl(aq). 2)Yes in a neutral solution, . There are equal amounts of protons and hydroxides in a neutral solution. 2 Reply Link to post Share on other sites More sharing options...
Tom Hiddleston Posted July 19, 2015 Report Share Posted July 19, 2015 Just to add on as clarification and to always remember for Bronsted-Lowry. Acids are proton donors. Bases are proton acceptors. Reply Link to post Share on other sites More sharing options...
