The process of osmosis over a semipermeable membrane.The blue dots represent particles driving the osmotic gradient. Osmosis (/ ɒ z ˈ m oʊ s ɪ s /, US also / ɒ s-/) [1] is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential ...
Thus, for every 1 mole of NaCl in solution, there are 2 osmoles of solute particles (i.e., a 1 mol/L NaCl solution is a 2 osmol/L NaCl solution). Both sodium and chloride ions affect the osmotic pressure of the solution. [2] Another example is magnesium chloride (MgCl 2), which dissociates into Mg 2+ and 2Cl − ions.
Osmotic pressure is an important factor affecting biological cells. [4] Osmoregulation is the homeostasis mechanism of an organism to reach balance in osmotic pressure. Hypertonicity is the presence of a solution that causes cells to shrink. Hypotonicity is the presence of a solution that causes cells to swell.
Early recipes for potato chips in the US are found in Mary Randolph's Virginia House-Wife (1824) [6] and in N.K.M. Lee's Cook's Own Book (1832), [7] both of which explicitly cite Kitchiner. [8] A legend associates the creation of potato chips with Saratoga Springs, New York, decades later than the first recorded recipe. [9]
Water potential is the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure and matrix effects such as capillary action (which is caused by surface tension).
Sun Chips contain about 30% less fat than regular potato chips. Plus, of the 6 grams of fat in each one-ounce serving, only 0.5 grams is saturated fat. Plus, of the 6 grams of fat in each one ...
Fouling of a membrane in different steps 1–5. 1) virgin membrane 2) pore narrowing 3) pore blocking 4) cake layer formation 5) cleaned membrane Membrane fouling is a process whereby a solution or a particle is deposited on a membrane surface or in membrane pores in a processes such as in a membrane bioreactor, [1] reverse osmosis, [2] forward osmosis, [3] membrane distillation, [4 ...
4. Original. Original SunChips, also known by the less flattering name of "plain," are amazing dippers. They have more depth of flavor than a potato chip, and unless we're talking about kettle ...
