Web1 Answer Sorted by: 5 Since p K a + p K b = 14, you get p K a = 10.64 for the methylammonium cation. H C l protonates methylamine. The amount of methylammonium increases by the same amount methylamine decreases. So p K a = p H + log ( [ H A] [ A X −]) = p H + log ( x 10 m m o l − x) WebThis calculation is based on a pH scale. The pH scale is logarithmic and shows the solution’s concentration of hydrogen ions inversely. More specifically, the pH of the solution is the negative logarithm to the base 10 of its hydrogen ion concentration in moles per litre. ... pH of weak base increases with increase in temperature due to ... small cats tail grassWebYou can estimate the pH value of the equivalence point according to the following rule: Strong acid reacts with weak base to form an acidic solution (pH < 7). Strong acid reacts with strong base to form an acidic solution (pH = 7). Weak acid reacts with strong base to form an acidic solution (pH > 7). small cat stencils
