Process of Osmosis

In osmosis, a solvent (often water) moves from a region of low concentration to a region of high concentration through a semi-permeable membrane. Here, water molecules diffuse into the concentrated sugar solution because the water molecules are small enough to move through the membrane. The larger sugar molecules are unable to move through the membrane into the water solution. Osmosis will stop when the two solutions reach equal concentrations on either side of the membrane.

Sucrose, a sugar with the formula C12H22O11, belonging to the group of carbohydrates known as disaccharides. It is ordinary table sugar, extracted from sugar beet or sugar cane. It is soluble in water, slightly soluble in alcohol and ether, crystallizes in long, slender needles, and is dextrorotatory, rotating the plane...
