WebA substance’s pKa value indicates how many acidic ions it will produce in a solution. Assume you have two solutions, one with the same number of sulfuric acid molecules and the other with citric acid molecules. Because sulfuric acid loses more protons to form more hydronium (H 3 O +) ions, the solution will be more acidic. WebFeb 23, 2024 · The K a value for the H S O X 4 X − ion would be the same whether we took H X 2 S O X 4 or N a H S O X 4. However, in the case of N a H S O X 4, there are no pre-existing H X + ions in solution when H S O X 4 X − deprotonates. Hence, it would be wrong to invoke the common ion effect here.
