Epsom salts is a hydrated ionic compound with the following formula: mgso4⋅x h2o. a 4.93-g sample of epsom salts is heated to drive off the water of hydration. the mass of the sample after complete dehydration is 2.41 g. find the number of waters of hydration (x) in epsom salts.

Calculate the expected ph values of the buffer systems from the experiments (a, b,c, d), using the henderson- hasselbalch equation, ph-pka+log[a-]/[ha]. use for pka values carbonic acid= 6.37, and acetic acid= 4.75.
