The pka of an acid whose ka = 10–11 is
1011
11
–11
3
–3

Option (b) is the correct answer.

Explanation:

Relation between and is as follows.

where,   is the acid dissociation constant.

As value of is given as . Therefore, calculating teh value of as follows.

                                   = -log ()

                                   = - (-11 × log (10))

                                   = 11

Thus, we can conclude that the of an acid whose is 11.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
