    Chemistry Comparing methods of computing pH at equivalence point in titration

    The pH at equivalence point is that of the hydrolysed salt. It is a salt, so the hydrolysis occurs only to the conjugate acid. BNH3+ + H2O <==> BNH2 + H3O+ The equilibrium is given by the constant Kh = [BNH2][H+]/[BNH3+] This constant is unknown, but as: BNH2 + H2O <==> BNH3+ + OH kb =...

    Why Does the Growth-Rate of a Titration Curve Vary?

    [/PLAIN] The curve represents the pH and in turn the pH is given by the -log[H+] So you would expect the curve to follow a logarithmic curve as the hydrogen ion concentration falls by an even amount. BUT the hydrogen ion concentration does not fall by an even amount as the volume of...

    Does the reaction between H2SO4 and NH4OH produces ammonia?

    no, they produce ammonium sulphate (a salt) this reaction is used to make fertilizer. If you have some NH4OH you already have a solution of ammonia in water. Simply heating this solution will give you ammonia. NH4OH --> NH3 + H2O
