Which of the following solids is soluble in water, conductive in solution, brittle and could have a melting point of 2800 C? (a) Ionic solid (b) Molecular solid (c) Covalent solid (d) Graphic solid Is the ionic solid Pb(OH)_2 soluble or insoluble...
Water is a polar molecule that forms many hydrogen bonds with itself and other polar substances, therefore,water is an excellent solvent for ionic and polar compounds. Unfortunately, benzophenone has no hydrogen bonding sites that are important for solubility in water. Even though the carbonyl group...
Write the correct formula for ammonium sulfate. Is it a molecular or ionic compound?Ammonium SulfateIt is an inorganic sulfate and it is obtained when ammonia reacts with sulfuric acid. This solid is very soluble in water and is commercially useful. It is used as a soil...
To know if it's positive or negative, we need to look at the makeup of tiny things that make up the substance. Molecular Structure of Methionine: The structure of methionine shows that it has different parts called functional groups, each playing a role in making the molecule polar. The ...
In recent years the molecular structure of the interface between biomolecules and water has been increasingly seen as an important component of sub cellular organization and function5,6,7. Water molecules localized to a hydration shell in the vicinity of a biomolecular “surface” are sometimes ...
Re-detachability is superior the ionicity high-molecular blendinging water suspension instillation medicinePURPOSE: To obtain an aqueous suspended eye drop by mixing an aqueous suspension with an ionic polymer and a metal cation, specifying viscosity, excellent in redispersibility of a slightly ...
Salts maintain the ionic strength of the solution which is needed to disrupt the molecular interactions in the sample. An optimal concentration of ionic salts is essential to disrupt cell membrane without damaging proteins of interest. When the salt ion concentration is too high, some proteins may...

The ionic composition of brines used to culture haloarchaeal strains GN-2 and GN-5 (which was determined to an accuracy level within the low-mM range; Javor, 1984) was used to calculate the water activity of these media (Figure 1a). The values obtained were consistent with the conversion...
