Web13 jul. 2024 · In this case, according to the required, we need to firstly tell that both Ca (ClO4)2 and HI undergo a complete ionization as the former is an ionic salt and the latter is a strong acid. Moreover, the HC2H3O2 is a weak acid, so its dissociation is not complete. In such a way, we can proceed as follows: a. Thus, the major species are Ca²⁺ and ClO₄⁻. WebA solution containing 2.665 g of CrCl3.6H2O (octahedral complex) is passed through a cation exchanger. The chloride ions obtained in solution react with AgNO3 and give 2.87 g of AgCl. Determine the structure of the compound and write its IUPAC name. Q8.

WebIs Ca3 (PO4)2 (Calcium phosphate) soluble or insoluble in water? The answer that Calcium phosphate is insoluble in water. Although it is an ionic compound, it does not dissociate … Calcium perchlorate is classified as a metal perchlorate salt with the molecular formula Ca(ClO4)2. It is an inorganic compound that is a yellow-white crystalline solid in appearance. As a strong oxidizing agent, it reacts with reducing agents when heated to generate heat and products that may be gaseous … Meer weergeven Calcium perchlorate is a strong inorganic oxidizing agent, enhancing the combustion of other substances that can potentially lead to explosion. The perchlorate ion, ClO−4, has a highly symmetrical tetrahedral structure … Meer weergeven Perchlorate salts are the product of a base and perchloric acid. Calcium perchlorate can be prepared through the heating of a mixture of calcium carbonate and ammonium perchlorate. Ammonium carbonate forms in the gaseous state, leaving … Meer weergeven Water Being very hygroscopic, calcium perchlorate is commonly seen in the presence of four water molecules, referred to as calcium perchlorate tetrahydrate Ca(ClO4)2·4H2O. Cyclic … Meer weergeven Electrolyte conductance Electrolyte conductance of Ca(ClO4)2 and double charged metal cations in the organic solvent acetonitrile has been tested. The interest in metal cation perchlorate interactions with photosensitive ligands has … Meer weergeven Calcium perchlorate is slightly toxic to humans, by ingestion or inhalation of dust particles, or (less so) by skin contact. Meer weergeven Web1 jan. 2024 · Under similar conditions, complexes of the form [(HL)2Ni]X2 (X = BF4, NO3, ClO4) were prepared from 2:1 ligand-metal ratios of Ni(BF4)2·6H2O, Ni(NO3)2·6H2O, or Ni(ClO4)2·6H2O. Deprotonation of the ligand with NaNH2 followed by reaction with NiI2 gives L2Ni when performed in Et2O, but leads to the co-crystal L2Ni·2[NCCHC(Me)NH2] … dch rally udvalg
