Qualitative analysis is used to identify and separatecationsandanionsin a sample substance. Unlikequantitative analysis, which seeks to determine the quantity or amount of sample, qualitative analysis is a descriptive form of analysis. In an educational setting, the concentrations of the ions to be i...
Scaling takes place due to the variety of anions and cations that the majority of the geothermal reservoir waters contain, and are prone to both precipitation and deposition when subjected to dramatic changes in temperature and pressure, causing failures to several parts of the plant. One of the...
The source attribution of observed variability of total PM2.5 concentrations over Halifax, Nova Scotia was investigated between 11 July-26 August 2011 using measurements of PM2.5 mass and PM2.5 chemical composition (black carbon, organic matter, anions, cations and 33 elements). ...

study11, likely due to limited exploration of the PES and the shallower and narrower energy basin – stemming from reduced crystal field stabilisation energy (Table3) due to weaker hybridisation between the anions and less diffuse 3dorbitals (compared to 4dand 5dfor Pd and Pt)....
and serve as anions to maintain charge neutrality.7,8,9The intrinsic characteristics of electrides should suggest superior electronic performances. However, the first proposed organic electrides were thermally unstable and air sensitive, constraining their technological applications.10,11,12In 2003, a ...
The acids that can be used to prepare pharmaceutically acceptable acid addition salts of such basic compounds are those that form non-toxic acid addition salts, i.e., salts containing pharmacologically acceptable anions, including but not limited to sulfuric, citric, maleic, acetic, oxalic, ...
A total of 30 samples were collected from the bore well of agricultural farmland and analysed for cations and anions. MH reveal that 53.33% of samples exceed the permissible level. PS shows that 43.33% of samples are marginally affected and 33.33% of samples are unsuitable for use in ...
The chemical analysis revealed that the major ions in the groundwater are Ca2+, Mg2+, Na+, and K+ (cations) and HCO3?, PO43?, Cl?, NO3? and SO42?(anions), and most of the groundwater samples (68.42%), revealed that the groundwater in the catchment is non- alkaline in nature,...
bothB1+andB3+cations form octahedral units. Usually, the perovskite has a structural phase transition upon tilting and rotating of the octahedral unit. As shown in Fig.1b, two possible crystal structures can be considered: one has a cubic space group; the other has an orthorhombic space group...
