reducing agent ; the concentrations of thiourea and formamidine disulphide in the solution are determined by analysis, eg by liquid chromatography, and an amount of oxidising agent or reducing agent is added to maintain the molar ratio of thiourea : formamidine disulphide to between 2:1 and 5:1...
The chemical properties of non-metals are: The number of electrons in the outer shell is usually 4-8 Conveniently gain or lose valence electrons When they come into contact with oxygen, they produce acidic oxides. High electronegative elements Excellent oxidising agents Q2: Write one example of ...
sulphides and oxides. Metallic Fe–Ni and troilite (FeS) are the most abundant metal-bearing phases in all three samples, particularly in the iron-rich meteorite. The samples were subjected to chemical micro-etching experiments with iodine and iron(III) chloride as oxidising agents in a DES ...

Dissimilatory iron-reducing bacteria (DIRB) have an important role in oxidising organic contaminants (e.g. aromatic hydrocarbons) in the subsurface and can also immobilise contaminant metals by reduction to less soluble forms (reviewed in 31., 39.). Geobacter spp. are the dominant organisms sel...
One of the most widely used methods for site-specific modification of glycan sites relies on the generation of an aldehyde group by oxidising the cis-glycol groups of terminal hexoses (Fig. 5a–c), commonly with sodium periodate [33], [98], [99], [100]. Download: Download high-res ima...
Another prime area where brazing innovation is essential is in the joining of components within Solid Oxide Fuel Cells (SOFCs, devices which produce electricity from oxidising a fuel, with higher efficiency and reduced environmental impact than most other power generation methods [Citation199]). With...
- stronger metallic bonding and bond - d electrons are more involved in M bonding What does high OS mean... tends to be a oxidising agent (strong oxidant) What does low OS mean... tends to be a reducing agent Page of 3 | Showing cards per page Previous | NextCram...
