No simple recipe exists for categorizing products and services, but there are some common product classifications in marketing: convenience, shopping, specialty and unsought products, according to âThe Advanced Dictionary of Marketing,â by Scott Dacko.onsiderations. The key is to categorize your products in ways that make sense for your business. This allows you to, for example, design separate marketing campaigns for each category of product you offer.
âA solvate is a single crystalline phase of a given compound of specific chemical structure in which a solvent molecule or molecules have been incorporated into the crystal lattice.â âIf you avoid it completely, and you get the solvate, then is it not reasonable to go back to example 1 where it tells you that if you washed it in water, you got the anhydrate?â
A solvation shell, in physical chemistry, is a structure used to describe solvation. A solvation shell is a shell of any chemical species that acts as a solvent and surrounds a solute species. When the solvent is water it is often referred to as a hydration shell or hydration sphere. A classic example is when water molecules form a sphere around a metal ion. The electronegative oxygen atom contained in the water molecule is attracted electrostatically to the positive charge on the metal ion. The result is a solvation shell of water molecules that surround the ion.
