View Solution Which metal will give blue colour metaborate in borax bead test ? View Solution Assertion : An aqueous solution of ferric chloride is acidic due to hydrolysis. Reason : Ferric chloride is a covalent compound and exists as a dimer. View Solution ...
The results revealed that the galena mineral exists as lead sulphide (PbS). The central composite design was employed for RSM modeling while back propagation (BP) coupled with the Levenberg-Marquardt (LM) algorithm was used to construct a feed-forward neural network (FFNN). The leaching ...
Ferric oxide, also known as hematite in its natural mineral form, appears as a reddish-brown solid under standard conditions. It is odorless, insoluble in water, and exists in a stable crystalline state. This compound is widely recognized for its high durability and heat resistance. Ferric ...
[Fe(OH)2]+, if it exists, is spectrophotometrically insensitive and is within the uncertainty of halide potentiometric studies. Certainly, the stability is much lower than is widely cited in the older literature. [Fe(OH)3]0 stability has been measured by solubility methods which are prone to...
Objective:The present work was undertaken to establish an animal model of basilar arterial thrombosis.Method:The bilateral carotid arterial of guinea pigs were ligated and 40%ferric chloride solution was applied to basilar artery topically. The blood flow of cochlea(CBF) was measured continuously with...
and its microscopic characterizations showed that Fe exists in an amorphous state, with the main valence state in the trivalent state, and Fe combines with Si and other non-metallic elements with different chemical bonds. The SEM showed that SPFC exhibits a rough porous reticulated structure. By...
used as a nutritional supplement. It is a new type of iron source, in which iron exists in the form of complex, does not catalyze oxidation reaction, and the color is very white, the application is wide, can be widely used in food, salt, health care products, medicine and other fields...
The results also suggest that there exists synergy between two components in the heterostructure for enhance catalytic performance. This novel material was used as heterogeneous catalyst for visible light driven oxidation of a number of alcohols by H2O2. The best ratio of the Fe(acac)3 and g-...
The natural formation of this resource was considered to be related to the weathering sedimentation process of carbonate that exists widely in Karst areas in southwestern China. Importantly, the lithium in carbonate-hosted clay-type lithium deposits has a weak binding force and occurs mainly in the...
Reactions are respectively:(2a)3FeII(OH)2+(1/2)O2⇌FeIIFeIII2O4+3H2O(2b)FeIIFeIII2O4+(1/4)O2⇌(3/2)γ-FeIII2O3 It is clear that no route exists to go merely from a GR to magnetite by aerial oxidation within solution. It has been claimed sometimes in corrosion science that...
