Question
Let the colour of the indicator HIn (colourless) will be visible only when its ionised form (pink) is 25% or more in a solution. Suppose HIn(pKa = 9.0) is added to a solution of pH = 9.6 predict what will happen (Take log 2 = 0.3)
Options
A.pink colour will be visible
B.pink colour will not be visible
C.% of ionised form will be less than 25%
D.% of ionised form will be more than 25%
