aDVnatgae Posted December 10, 2011 Report Share Posted December 10, 2011 Hiwhat will happen in this reaction2 NaOH + H2SO4 → Na2SO4 + 2 H2Owhen I increase the concentration of one of the reactants. They form salt and water will a pH of 7.But if I increase the concentration of one of the reactants? will it effect the pH? Reply Link to post Share on other sites More sharing options...
Avan:) Posted December 10, 2011 Report Share Posted December 10, 2011 Yes it will. the higher the concentration of acid or H+, the lower the pH the higher the concentration of base or OH-, the higher the pH pH is basically another way of expressing concentration values, so it makes when it does. 1 Reply Link to post Share on other sites More sharing options...
Keel Posted December 10, 2011 Report Share Posted December 10, 2011 To answer the question you basically need a mole balance to determine whether either of the reactants are in excess. If one of the reactants has a higher number of moles than the other then this reactant is in excess and the pH will lean towards the charateristics of this reactant. Thus, you must consider both volume and concentration as moles = volume x concentration. 1 Reply Link to post Share on other sites More sharing options...
