Ibuprofen (also known as Brufen) is an analgesic (pain killer) and anti-inflammatory drug. It is a weak carboxylic acid (Chemical Formula: C12H17C00H; K = 1.2 x 10-5). A Medical student from Lusaka Apex Medical University (LAMU) prepared a 0.4 M solution of Brufen to give to an accident victim with minor injuries but in a lot of pain. on i. Write a reaction equation showing how Brufen ionizes in water. ii. Write the acid ionization constant expression for Brufen iii.
