CHEMISTRY GLOSSARY
electrode of the second kind → elektroda drugog reda
Electrodes of the second kind are metal electrodes assembly with the equilibrium potential being a function of the concentration of an anion in the solution. Typical examples are the silver/silver-chloride electrode and the calomel electrode. The potential of the metal is controlled by the concentration of its cation in the solution, but this, in turn, is controlled by the anion concentration in the solution through the solubility product of the slightly soluble metal salt. Contrast with electrode of the first kind and electrode of the third kind.
electrode of the third kind → elektroda trećeg reda
Electrode of the third kind is a metal electrode assembly with the equilibrium potential being a function of the concentration of a cation, other than the cation of the electrode metal, in the solution. The assembly consists of a metal in contact with two slightly soluble salts (one containing the cation of the solid metal, the other the cation to be determined, with both salts having a common anion) immersed in a solution containing a salt of the second metal (e.g., zinc metal--zinc oxalate--calcium oxalate--calcium salt solution). The potential of the metal is controlled by the concentration of its cation in the solution, but this is controlled by the anion concentration in the solution through the solubility product of the slightly soluble metal salt, which, in turn is controlled by the concentration of the cation of the second slightly soluble salt. These electrodes are very sluggish and unstable due to a series of equilibria to be established to produce a stable potential.
homogenic reaction → homogena reakcija
Homogenic reactions are those reactions in which products and reactants are in the same phase (aggregate state).
honey → med
Honey is a sweet, amber colored, viscous fluid produced by honeybees from the nectar of flowers. It is composed primarily of fructose (about 40 %), glucose (about 35 %), and water (up to 20 %). In addition, honey contains sucrose, maltose, trisaccharides, and small amounts of minerals, vitamins, and enzymes.
electrodeposition → elektrodepozicija
Electrodeposition is a process of depositing solid materials on an electrode surface using electrolysis. It is a somewhat loosely used term that is applied to many technologies. There are a number of metal deposition technologies. However, not only metals but also different compounds can be electrodeposited. This is used most often for the formation of oxides (such as manganese dioxide and lead dioxide) by anodic oxidation of dissolved salts.
electrodialysis → elektrodijaliza
Electrodialysis is a procedure of dialysis accelerated with an electric field. Dialyser is divided into three sections. Solution flows through the middle section, between two semipermeable membranes alternately to positive ions and negative ions. An electrodes are placed in the neighbouring sections. Under the influence of electric field, positive ions will travel towards the cathode (the negative electrode), and negative ions towards the anode (the positive electrode), whereby travelling of ions through the membrane is accelerated. In this way, the feed water is separated into two streams: one of pure water and the other of more concentrated solution.
hydrophilic → hidrofilan
Hydrophilic is having a strong tendency to bind or absorb water, which results in swelling and formation of reversible gels. This property is characteristic of carbohydrates.
hydrophobic → hidrofoban
Hydrophobic is antagonistic to water, incapable of dissolving in water. This property is characteristic of oils, fats, waxes, and many resins.
ideal crystal → idealni kristal
Ideal crystal is a single crystal with a perfectly regular lattice that contains no impurities, imperfections, or other defects.
