Thanks in advanceLearning Goal: Another way to express acid strength is by using pk To understand the relation between the strength of an acid or a base and its pK, and pK, values. The degree to which a weak acid dissociates in solution is given by its acid-ionization constant, K. For the generic weak acid. HA. pk. = log K. Another way to express base strength is by using pk log K HA(ag) A (aq) + H'(aq) and the acid-ionization constant is given by Part A IA H HA K. Similarty, the degree to which a weak base reacts with HO in solution is given by its base-ionization constant, K. For the generic weak base, B. A new potential heart medicine, code named X-281, is being tested by a pharmaceutical company. Pharma pill. As a research technician at Pharma-pil you are told that X-281 is a monoprotic weak acid, but because of security concerns, the actual chemical formula must remain top secret.
