The idea of concentrations and the gradients within them is important when understanding the movement of particles or molecules across cell membranes. A solution with a low solute concentration has a ...

\(concentration~in~g/dm^3 = \frac{mass~of~solute~in~g}{volume~in~dm^3}\) The units for concentration can also be shown as g dm-3, but this means the same as g/dm 3. 8 g of sodium hydroxide is ...

The film explores the concept of solutions in chemistry, defining key terms such as solute and solvent. It illustrates how solute particles dissolve and disperse uniformly in a solvent, highlighting ...

Taylor Dispersion Analysis (TDA), or Taylor-Aris dispersion, is a technique for rapidly determining the diffusion coefficients of molecules. From the diffusion coefficient values, hydrodynamic radii ...

Human cells dwell in salt water. Their well-being depends on the ability of the body to regulate the salinity of extracellular fluids. By controlling water intake and excretion, the osmoregulatory ...
