If a caption or explanation is included this helps, but please use your discretion.īefore asking about chemical drawing/illustration programs, look at your school's IT/software website and see if they provide an institutional license of ChemDraw (hint: if they have a chemistry department, they will) As they react, the larger particles form nonspherical structures whose surfaces react with water less readily and less uniformly than the surfaces of the smaller, spherical particles, he said. Swihart said the discrepancy is due to geometry. Likewise, simple pictures of uninteresting and garden variety chemistry-related things are not appreciated. The maximum reaction rate for the 10-nanometer particles was about 150 times as fast. No memes, rage comics, image macros, reaction gifs, or other "zero-content" material. However, academic discussions on pharmaceutical chemistry and the science of explosives are permitted. Because of this the important issue in the. On the other hand, it is somewhat problematic, mostly due to its reactivity with water. Air and other reagents can oxidize acidified solution of iodide ions.Rules: Violating a rule will result in a ban.Īsk homework, exam, lab, and other undergraduate-level questions at ChemicalForums otherwise it will be deleted.ĭiscussions on illicit drug synthesis, bomb making, and other illegal activities are not allowed and will lead to a ban. Aluminium nitride is an interesting and useful ceramic material. It has the lowest standard reduction potential of the halogens, and is therefore the least powerful oxidizing agent. If a metal is above hydrogen in the reactivity series it should, in principle, be able to remove the oxygen from the water to leave hydrogen gas. Chlorine reacts reversibly with water to produce acids as in the following example, in which chloric acid and hydrochloric acid are formed: These solutions are good oxidizing agents. The alkali metals are soft reactive metals, they react vigorously with water and become more reactive as you go down the group HighSchoolDiploma GCSE. These solutions form solid hydrates within an ice lattice. The oxygen seen in the reaction is produced from the decomposition of the hydrogen peroxide in a side reaction. Another suggests a the priciptates is \(CoO(OH)\). One resource describes it as a 'hydrous \(Co2O3\), i.e., cobalt(III) oxide with closely associated water. The reaction of water with chlorine, shown below, proceeds very slowly.Ĭhlorine and bromine are moderately soluble in water. The nature of the precipate of thie reaction is under. However, fluorine and chlorine have larger reduction potentials, and can oxidize water.įluorine reacts with water vapor to form oxygen and ozone: Thus, iodine and bromine do not react with water. \)įrom a standard reduction potential table, it is determined that iodine and bromine cannot oxidize water to oxygen because they have smaller reduction potentials than oxygen.
