What does it mean to say that water autoionizes? view available hint(s) what does it mean to say that water autoionizes? water will cause many ionic compounds to dissociate without additional input of energy. water is a good conductor of electricity; and when it conducts, it ionizes. water is polar, similar to an ion being polar. therefore, it is autoionic. a water molecule can donate a proton to another water molecule, forming h3o+ and oh− in solution.

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
