Question

Allylamine, C3HjNH2, is a weak base. A 0.74 M aqueous solution of allylamine has a pH of 12.20. What is K, for allylamine? Calculate the pH of a 0.82 M aqueous solution of allylamine. Kb = pH =

Answer

The value of kb is 12.94 and the value of ph is 0.76. Explanation: The parameter kb is a constant known as the base dissociation constant or the equilibrium constant for the dissociation of a base. It is also referred to as the alkaline dissociation constant. The value of kb indicates the strength of a base, with higher values corresponding to stronger bases. The parameter ph is a measure of the acidity or basicity of a solution. It is defined as the negative logarithm of the concentration of hydrogen ions in the solution, with values ranging from 0 (highly acidic) to 14 (highly basic). A ph value of 0.76 indicates that the solution is slightly acidic.
