Osmosis is the process by which a liquid moves through a semi permeable membrane. Several factors affect osmosis including temperature, surface area, difference in water potential, pressure and concentration gradient.Continue Reading
Osmosis occurs when there is a high solute concentration area on one side of a membrane and a low solute concentration area on the other. The higher the temperature, the faster that osmosis occurs. This is due to the amount of energy present in the water, as energy is expended to permeate the membrane.
Surface area affects the rate of osmosis directly. The larger the surface area, the easier is it for molecules to cross the membrane. Conversely, the smaller the surface area, the more difficult it is for molecules to cross the barrier. The disparity of water concentration, or difference in water potential, is a large factor in the speed of osmosis. The greater the disparity, the faster osmosis will occur.
Pressure directly affects the rate of osmosis. The higher the pressure on one side of the membrane, the more rapidly osmosis takes place to the other. The same is true for concentration gradient, the lower the concentration of solute in water, the faster it moves through a membrane.Learn more about Solutions & Mixtures
Osmosis is an example of simple diffusion. Simple diffusion is the process by which a solution or gas moves from high particle concentration areas to low particle concentration areas. This is also known as passive diffusion. A drop of red dye turning water pink is an example of the simple diffusion process.Full Answer >
Osmosis affects cell volume in both plant and animal cells, allows for the storage of red blood cells outside of the body and preserves meats and fruits through dehydration. Reverse osmosis is used to desalinate water. Life would not be possible without osmosis.Full Answer >
The most common methods of removing salt from water are distillation and reverse osmosis. Distillation refers to the process of purifying water through evaporation and condensation, while reverse osmosis uses a semi-permeable membrane to remove salt and other particles from water.Full Answer >
Solute potential is defined as the pressure that must be applied to a solution to prevent the inward flow of water through a semipermeable membrane. The flow of water stops because the pressure of the solution and the pressure of the water are equal. Osmotic potential is another term for solute potential.Full Answer >
