Barbituric acid (K_a = 9.8 × 10^-5) is used in the preparation of barbiturate drugs, which act as central nervous system depressants.

Determine the % ionization for a 0.0015 M solution that has a pH of 3.78.

Please give the answer to 2 decimal places.

Barbituriensuur (K_a = 9.8 × 10^-5) word gebruik in die bereiding van barbituraatmedisyne, wat dien as depressante in die sentrale senuweestelsel.

Bepaal die % ionisasie vir 'n 0.0015 M oplossing met 'n pH van 3.78.

Gee asseblief die antwoord tot 2 desimale plekke.
