Question

Consider the K_a values for the following acids:

Write the formula for the acid which has the STRONGEST conjugate base.

What is the corresponding K_b value for the strongest acid from the table above?

Answer 1

Answer #1

Answer:-

The acid which give strongest conjugate base = HB

because it has smallest Ka value because lower the Ka value, weaker is the acid and stronger will be its conjugate base.

strongest acid = HD because it has highest Ka value.

Kb = Kw/Ka

= 1.00E-14/2.84E-4

= 3.52E-11

in some cases, there may be a mixture of two or more acids. When this happens, the stronger acid will dissociate completely, so you should be able to calculate how much H,0 is in solution as a result. Writing out the equation for the dissociation often helps The weak acid will attempt to dissociate and is governed by the equilibrium (K,). You should write out the equation for the weak acid Now-write in the values for the concentrations that you'll...
