Question

Bromcresol purple is a weak acid and can act as an acid-base indicator. The yellow acidic form is equal in amount to the purple base form when the pH is equal to 6.3. Determine the pK_{a} for bromcresol purple.

Accepted Answer

pK_{a} = 6.3

Answer

pK_{a} = 7.7

Answer

pK_{a} = 3.1

Answer

pK_{a} = 12.6
