The pKa of a compound whose acidic or basic form absorbs UV or visible light can be determined spectroscopically because ________.
◦ the pKa is the same as the pH at which half of the total absorbance increase occurs
◦ absorbance of the basic form is always twice that of the acidic form
◦ delocalization always leads to a decrease in acidity
◦ absorbance of the acidic form is always twice that of the basic form
◦ λmax always decreases as the acidic form is converted to the basic form

Hypertension is a silent killer because it is deadly and has no significant early symptoms.
