WebAn acid or base's strength refers to its degree of ionization. A strong acid will completely ionize in water while a weak acid will only partially ionize. Since there are different degrees of ionization, there are different levels of weakness. Fortunately, there is a simple quantitative way of expressing this. WebThe compound which is dissolved in a solvent produces positive and negative ions called electrolytes and the degree of ionisation is defined as the ratio of a number of molecules undergoing dissociation to a total number of molecules. 𝞪 = number of molecules undergoing dissociation/ total number of molecules
