Lead and manganese oxides may also be oxidized to peroxides by the action of oxygen, and in this event might act as very active catalyzing agents or carriers of oxygen.
It consists largely of pinene and isomeric terpenes, and has the property of attracting oxygen, with the formation of peroxides which stimulate the drying of oils.
This mixture of the two peroxides may be kept dry in a stoppered bottle for any length of time.
In these cases the ozone is converted into ordinary oxygen, and the peroxides into monoxides.
Boettger states that when a mixture is made of equal weights of the peroxides of lead and barium, and dilute HNO{3} of a strength of 9 deg.
The presence of peroxides of the heavy metals is prejudicial, since they tend to increase the quantity of silver retained in the slag.
Peroxides of iron, manganese, and copper interfere by counteracting the effect of the charcoal or flour, and thus reducing the size of the lead button.
TABLE 7 Peroxides Giving Light with Pyrogallol and Oxidizers Key to column headings: [A]: Oxidizer.
Metallic peroxides are also capable of evolving oxygen on heating with sulphuric acid.
This reaction usually proceeds with greater ease than the decomposition of peroxides by heat alone.
This takes place, for instance, in the decomposition of salts of silver and manganese by the galvanic current, peroxides of these metals being formed.
Peroxides are able to evolve oxygen at a more or less elevated temperature.
Peroxides are the highest oxides of certain metals; those metals which form them generally give several compounds with oxygen.
Metallic chlorides corresponding with the peroxides either do not exist, or are easily decomposed with the disengagement of chlorine.
From this it is evident that there should exist such chlorine compounds as would evolve chlorine as peroxides evolve oxygen, and indeed a large number of such compounds are known.
Neither calcium nor strontium oxides are able to give such a peroxide directly, but they form peroxides under the action of hydrogen peroxide.
Peroxides of lead and manganese, and other analogous peroxides (see Chap.
Peroxides of calcium and strontium may be obtained by means of hydrogen peroxide.
Peroxides contain more oxygen than the bases formed by the same metals.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "peroxides" in a variety of sentences. We hope that you will now be able to make sentences using this word.
