A 1.2 M solution of a weak base B is prepared. Using a pH meter, the pH is measured to be 11.82. Calculate the base ionization constant

Kb = 3.64x10⁻⁵

Explanation:

First we calculate the pOH of the solution:

Then we calculate [OH⁻]:

For a weak base solution with a relatively high concentration, we can use the following formula:

Where C is the concentration of the weak base solution (1.2 M in this case).

With the formula above we can calculate Kb:

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

explanation:

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
