Results 51–60 of 167 for aliciklički spojevi

ferrous → fero

Ferrous is the term or prefix used to denote compounds of iron in which iron is in the divalent, Fe(II), state, for example, ferrous sulfate, FeSO₄.

fractional crystallisation → frakcijska kristalizacija

Fractional crystallisation is a method of separating a mixture of soluble solids by dissolving them in a suitable hot solvent and then lowering the temperature slowly. The least soluble component will crystallise out first, leaving the other components in the solution. By controlling the temperature, it is sometimes possible to remove each component in turn.

chlorine → klor

Chlorine was discovered by Carl William Scheele (Sweden) in 1774. The origin of the name comes from the Greek word chloros meaning pale green. It is greenish-yellow, disagreeable gas with irritating odour. Gas is toxic and severe irritant by contact or inhalation. Never found in free form in nature. Commercial quantities of chlorine are produced by electrolysis of aqueous sodium chloride (NaCl) from seawater or brine from salt mines. Used in water purification, bleaches, acids and many, many other compounds such as chlorofluorocarbons (CFC).

chromium → krom

Chromium was discovered by Louis-Nicholas Vauquelin (France) in 1797. The origin of the name comes from the Greek word chroma meaning colour. It is very hard, crystalline, steel-grey metal. The pure metal has a blue-white colour. It is hard, brittle and corrosion-resistant at normal temperatures. Hexavalent compounds toxic by skin contact. The most important chromium mineral is chromite [Fe,Mg(CrO₄)]. Produced commercially by heating its ore in the presence of silicon or aluminium. Used to make stainless steel. It gives the colour to rubies and emeralds. Iron-nickel-chromium alloys in various percentages yield an incredible variety of the most important metals in modern technology.

cobalt → kobalt

Cobalt was discovered by Georg Brandt (Germany) in 1735. The origin of the name comes from the German word kobald meaning goblin or evil spirit. It is hard, ductile, lustrous bluish-grey metal. Surfaces stable in air. Reacts over time with dilute acids. It has remarkable magnetic properties. Cobalt occurs in compounds with arsenic and sulfur as in cobaltine (CoAsS) and linneite (Co₃S₄). Pure cobalt is obtained as a by-product of refining nickel, copper and iron. Used in many hard alloys; for magnets, ceramics and special glasses. Radioactive cobalt-60 is used in cancer therapy.

complexometry → kompleksometrija

Complexometry is a volumetric analytic method which is based on titration of metal ion solutions with a substance that, combined with metal ions yields complex compounds, e.g. EDTA. The stoichiometric ratio of EDTA-metal in complexometric analyses is always 1:1, whatever the valency of the metal

Meⁿ⁺ + H₂Y^2- →← MeY^(n-4) + 2H⁺

glycols → glikoli

Glycols are compounds that have two hydroxyl groups present in each molecule. The simplest member is ethylene glycol.

HOCH₂CH₂OH

herbicide → herbicid

Herbicide is any chemical compound used to kill pests that destroy agricultural production. Pesticide include herbicides (such as 2.4 D and Paraquat), which kill unwanted plants or weeds.

hydrocarbon → ugljikovodici

Hydrocarbon is a compound containing only carbon and hydrogen.

inorganic chemistry → anorganska kemija

Inorganic chemistry, the branch of chemistry concerned with compounds of elements other than carbon. Certain simple carbon compounds, such as CO, CO₂, CS₂, carbonates CO₃^2- and cyanides CN^-, are usually treated in inorganic chemistry.
