Ionization examples chemistry
WebChemical ionization uses a reagent gas to ionize sample molecules through ion–molecule reactions in the gas phase. The reagent gas (e.g., methane) first undergoes electron ionization, generating a molecular ion which then fragments and/or reacts with other reagent gas molecules and ions. WebAutoionization of Water Examples. Time to pull together what we have learned by practicing some example calculations involving the autoionization of water. Unless stated otherwise, assume that the temperature is 25 °C in all the following questions. First, have a go at finding pH using K w and [OH-]. Here are the steps:
