2019/10/31· The calcium hydroxide can also be provided as calcium oxide. The actual stoichiometric excess of metal can vary considerably, for example from 0.1 to about 30 or more molar equivalents, in particular more than 0.5, so that a total base nuer (TBN) is set.
Is calcium sulfate an ionic or covalent compound? | Socratic
2018/6/22· Ionic Calcium sulfate is a compound with the chemical formula of CaSO_4. It is made up of a calcium ion (Ca^(2+)) and a sulfate anion (SO_4^(2-)). When a compound is made up of a metal ion and a polyatomic anion, the compound is considered to be ionic. However, the compound itself has both ionic and covalent bonds in it.

In binary compounds of metal and non-metal, the metal atom has positive oxidation nuer while the nonmetal atom has negative oxidation nuer. For example, O.N. of Kin KI is + 1 but O.N. ofl is -1. In binary compounds of non-metals, the more electronegative atom has negative oxidation nuer; but less electronegative atom has positive oxidation nuer.

Fluorescent Sensors for Measuring Metal Ions in Living …
Because many metal sensors involve a change in brightness upon metal binding, we report brightness in the metal-free and metal-bound state. However, there may be differences in the photophysical properties of a sensor in vitro (i.e., in a cuvette) versus in situ (i.e., inside a cell) due to differences in viscosity, pH, solvent, accessibility to oxygen, or other factors associated with the

Reactivity Series of Metals - Get the Chart, Significance …
In the reactivity series, as we move from bottom to top, the reactivity of metals increases. Metals present at the top of the series can lose electrons more readily to form positive ions and corrode or tarnish more readily. They require more energy to be separated from their ores, and become stronger reducing agents, while metals present at the bottom of the series are good oxidizing agent.
