Question 10 of 32The base dissociation constant, Kp, of CH3NH₂ is 4.4 x 10-4. What does theKb value indicate about this compound?OA. CH3NH₂ is a weak base.B. CH3NH₂ is a strong acid.C. CH3NH₂ is a strong base.OD. CH3NH₂ is a weak acid.

Respuesta :

The Kb value is an indicator which tells how strong is a base. The homologue for the acids is the Ka.

When a base is completely dissociated in the medium, it is considered a strong base and its Kb is going to be very high. For example, for the NaOH the Kb is 0.63.

4.4*x10-4 is a very low number compared to 0.63. It means that the CH3NH2 is a weak base.
