Q54.Uracil is base present in RNA with the following structure. % of N in uracil is _______.

What This Question Tests

The question involves a buffer solution, requiring the use of the Henderson-Hasselbalch equation to calculate the dissociation constant (Ka) of acetic acid given the pH and concentrations of the acid and its salt.

Concepts Tested

Henderson-Hasselbalch equationDissociation constant (Ka)pH calculation for buffer solutions

Formulas Used

pH = pKa + log([Salt]/[Acid])

pKa = -log(Ka)
