Atco Barometer 1651, Thus substituting 0.10 M in the equation for Ka1 for the concentration of H2S, which is essentially constant regardless of the pH, gives the following: Substituting this value for [H+] and [HS] into the equation for Ka2, \[K_{\textrm{a2}}=1.3\times10^{-13}=\dfrac{[\mathrm{H^+}][\mathrm{S^{2-}}]}{[\mathrm{HS^-}]}=\dfrac{(1.1\times10^{-4}\textrm{ M})x}{1.1\times10^{-4}\textrm{ M}}=x=[\mathrm{S^{2-}}]\]. padding: 8px; 2. Few are as follows: Arrhenius acids: According to Arrhenius, the Arrhenius acids are the acids which give ions when the acids are dissolved in the water. If a strong acid and strong base are titrated, the pH of the solution will be 7.0 at the equivalence point. The pKa of the weak acid should be as close as possible to the desired pH, the point in a titration where the number of moles of hydrogen ions equals the number of moles of hydroxide ions, the point in a titration at which an indicator changes color, The solubility of a slightly soluble compound can be increased by adding a ligand (molecule or ion) that forms a(n), The pH at the equivalence point for a weak point for a weak acid-base titration is ____ than 7.00 because at this point the major species in solution is the conjugate ____ of the weak acid. no precipitate will form because the solution is unsaturated, the solution is saturated and no change will occur, a precipitate will form until the remaining solution is saturated.
