inorganic chemistry - Is magnesium sulfate basic, neutral or acidic?


A question in my college test was whether MgSOX4 is neutral, acidic or basic. I was told to solve this kind of problem by hydrolyzing any ions that do not "come from" a strong acid or a strong base, and if nothing is hydrolyzed, then the salt is neutral. So by this logic, as MgX2+ comes from Mg(OH)X2 and SOX4X2 comes from HX2SOX4, I answered "neutral".



My professor marked it as wrong, and said that the salt MgSOX4 is basic. How can you explain this?
