Calculate the percent ionization of 0.0075 M butanoic acid i - Quizlet
WebAug 14, 2024 · Measurements of the conductivity of 0.1 M solutions of both HI and HNO_3 in acetic acid show that HI is completely dissociated, but HNO_3 is only partially dissociated and behaves like a weak acid in this solvent. This result clearly tells us that HI is a stronger acid than HNO_3. WebJan 29, 2006 · sci0x. 83. 5. Question: Aspirin is a weak acid.
