Penetration - Shinto

When a pure solvent and a solution (or a dilute solution and a concentrated solution) come into contact with each other across a semipermeable membrane, the solvent spontaneously moves through the semipermeable membrane in the direction of diluting the solution. This is a general property of solutions. As a result of osmosis, the pressure on the solution side increases. Conversely, to prevent osmosis, excess pressure must be applied to the solution side. The osmosis of water from water through an animal membrane (e.g., pig bladder membrane) into a sugar solution is the most well-known example. [See other terms] Osmotic pressure, osmometer

純溶媒と溶液(あるいは希薄溶液と濃厚溶液)が半透膜を隔てて接するとき，溶液を薄める方向に半透膜を通して溶媒が自発的に移動する現象．溶液の一般的性質である．浸透の結果，溶液側の圧力は高まる．逆に，浸透を阻止するためには溶液側に過剰圧を加える必要がある．動物膜(例；ブタの膀胱膜)を通しての水から砂糖水溶液への水の浸透は，もっともよく知られた例である．[別用語参照]浸透圧，浸透圧計
