SOLUTION:
pKIn must be
midpoint of pH range for acidic indicators and pOH range for basic indicators
The pH range = 4 to 6.5 so pOH
range is 10 to 7.5
Hence PkIn = (10+7.5) /2 = 8.75
(1) A fascinating discovery was the synthesis of spherical carbon-cage molecules called fullerences. The discovery of fullerene was awarde...
