Derive ostwald's dilution law for ch3cooh
WebEquation: Ostwald’s Dilution Law Ostwald’s dilution law is as follows: 𝐾 = 𝛼 1 − 𝛼 𝑐 𝐾 is the acid dissociation constant of the acid. 𝛼 is the degree of dissociation of the weak acid at equilibrium. 𝑐 is the total concentration of weak acid. WebOstwald’s Dilution Law: Degree of Dissociation. Ostwald’s dilution law is the application of the law of mass action to weak electrolytes in solution. A binary electrolyte AB which dissociates into A + and B – ions. AB ⇌ A + + B – (i) For very weak electrolytes, since α <<< 1, (1 – α) = 1. ∴
