hi i was wondering of anyone could help me with my planning exercise. i am ment to find the % purity of Magnesium Carbonate in an idigestion tablet. and i have to do a reaction with acid. i was going to use one molar HCL but my teacher told me i shud use a stronger acid, i was wondering if anyone could tell me why it would be better to use a stronger acid. my teacher mentioned something about it being more concentrated, more moles in a smaller volume. but how would this aid with the reaction? someone help! :confused: sezzie69
