Only freshly prepared nitroprusside should be administered, and the container should be covered with lightproof materials, since they are decomposed upon exposure to light. Solutions may be discolored due to the presence of organic and inorganic substances and must not be used. Preservatives, such as sodium bisulfate and hydroxy benzoates, reduce the stability of nitroprusside.124 126... 

Figure 12. Volume of hydrogen evolved from irradiating in 25 mL of solution containing 0.1 M (pH 3) and 25 mg of CdS loaded with 0.025 mg of RuOtin visible light. Solution was briefly deaerated prior to illumination by flushing with...

A white or yellowish, slightly hygroscopic, microcrystalline powder. It darkens with age and on exposure to light. Solutions in water and ethanol give a blue fluorescence. M.p. about 185, with decomposition. 

In this context, a frankly empirical approach was adopted by earlier workers not yet blessed by Debye and Huckel s light. Solutions that obeyed Eq. (3.52) were characterized as ideal solutions since this equation applies to systems ofnoninteracting solute particles, i.e., ideal particles. Electrolytic solutions that do not obey the equation were said to be nonideal. In order to use an equation of the form of Eq. (3.52) to treat nonideal electrolytic solutions, an empirical correction factor was introduced by Lewis as a modifier of the concentration term ... 

Properties White, fine crystals or powder odorless relatively stable to air and light solutions dextrorotatory. Sparingly soluble in water slightly soluble in alcohol fairly soluble in chloroform. 

Properties A white, crystalline powder odorless slight salty taste followed by sweetish aftertaste. Decomposes on exposure to light, solutions are neutral to litmus. Soluble in water very soluble in methanol slightly soluble in alcohol practically insoluble in acetone, ether, and benzene. 

In some situations, there are also light solutions to realize these support concepts - e.g. batch XML transformators for specific and simple cases of integrators. They have been solved by manual implementation. If we would try to incorporate them into the general modeling approach would the modeling layers, the problems in these layers, and the transition between layers be the same ... 

Ammonium reineckate (Reineckate salt) [13573-16-5] M 336.4 (anhydrous), m 270-273°(dec). Crystallise it from water, between 30° and0°, while working under artificial light. Solutions of reineckate salt (aqueous or alcoholic) decompose slowly at room temperatore in the dark ( 2 weeks) and more rapidly at higher temperatures or in diffuse sunlight. The solutions aie blue in colour and liberate HCN (POISONOUS). Store it dry in the dark under a vacuum. [Dakin Org Synth Coll Vol II 555 19431]... 

Pour light solution in back chamber of gradient maker, add stirbar balancer. 

Brown, dark-brown, or almost black, odorless, lustrous scales or granules somewhat hygroscopic. Freely sol in water. Almost insol in alcohol, chloroform, ether. Keep well closed and protected from light. Solutions should be freshly made and protected from light. 

CHEMICAL PROPERTIES combustible solid rapid oxidation in presence of alkali and light solution becomes brown in air and oxidizes to quinone FP (165°C, 329°F) AT (515.6 C, 960°F). 

In the crystalline form the heteronuclear gold cluster compounds are air-stable at ambient temperature and not sensitive to light. Solutions, however, decompose slowly under action of light to form gold metal. 

Stability of Dexamethasone - The following reported stability Information is entirely consistent with the potential reactivity discussed above. Dexamethasone solid is reported to be stable in air but should be protected from light. Solutions of dexamethasone lose about 50% of the C-17 a-ketol side chain within 5-8 minutes in the presence of a base catalyst.Excellent stability is shown by dexamethasone in a variety of marketed pharmaceutical dosage forms. Wahba has compared the thermal stability of dexamethasone in four different tablet formulations. ... 

Stability and solubility determinations performed as necessary to ascertain fate and distribution of a chemical under specific conditions (time duration, temperature, light, solution media, etc.) as required for the particular bioassay experiment. 

Solvent cementing of parts of polycarbonate may be effected by the use of a variety of solvents or light solutions of polycarbonate in solvents. Methylene chloride, a 1-5% solution of polycarbonate in methylene chloride, and a mixture of methylene chloride and ethylene dichloride (with a maximum of 40% ethylene dichloride) are commonly recommended.
