Determining the Formula of a Hydrate

A hydrate is an ionic compound that has a definite amount of water molecules attached to its crystalline structure. The ratio of water mol ecules to the anhydrous salt is constant. Many compounds exist as hydrates. Some examples are copper (II) sulfate, sodium sulfate, nickel (II) sulfate, iron (II) sulfate, cobalt (II) chloride, magnesium sulfate,

When these reactions are completed is it often necessary to purify the resulting product, separating the side-products, left over reagents and or consumed reagents from the desired product. Similarly in the natural work it is rare to find a compound in a pure form. The techniques used

Stripping for Reprobing - Abcam

blotting multiple gels have the advantage of saving samples, materials, and time. It is not advisable to make quantitative comparisons of targets probed before and after stripping since the procedure removes some sample protein from the membrane. For the same reason, a stripped membrane should not be probed to demonstrate the absence of a protein.
