Solution gaseous

Different results can be found in the solid state and solution gaseous HX (X= halide) adds cis to solid IrCl(CO)(PPh3)2 and in benzene solution, but in polar solvents like methanol a mixture of cis- and trans-products is found. 

To obtain a sample solution, gaseous samples are usually passed at a controlled flow-rate through a suitable absorption solution. For example, when determining the concentration of sulphur dioxide in the atmosphere, the air is passed through a tetrachloromercurate solution and sulphur dioxide is trapped as a result of the reaction... 

Copper and Iron. — Dissolve the palladium in nitrohydrochloric acid, and evaporate the excess of acid on the water-bath. Dissolve the residue in water, and add ammonia water until the flesh-colored precipitate of ammonium palladous chloride first formed redissolves. Then pass into the solution gaseous hydrochloric acid, whereby the palladium is precipitated as yellow palladosainine chloride, while iron and copper remain in solution. The precipitate is filtered off,... 

Metal alkoxides themselves — the derivatives of metal and aliphatic alcohols. The character of M-OR bonding in them is intermediate between phenoxides and esters. Their properties are varied, but almost all of them are sensitive to the action of water and, normally, aggregated in solution, gaseous, and solid phases. 

How does temperature normally affect solubility of solid solutes Gaseous solutes ... 

AN solution must be stored at a temperature above the crystallizing temperature of the solution. Gaseous ammonia is normally added in small quantities to maintain the solution at the correct pH because AN solutions lose ammonia during storage.103 Steps should also be taken to avoid contamination by decomposition catalysts such as chlorides and organic materials. 

PGSS = particles from gas-saturated solution (gaseous CO2 is dissolved in a melted drug and the gas-saturated solution is expanded). 

Environmental aspects of vanadium chemistry include vanadium chemistry in solution, gaseous, and solid states, and thus span a wide range of the properties of vanadium compounds. The recent compendium of reviews of the environmental chemistry of vanadium has shown that this area does have many contributors (contributed to and edited by Nriagu). Vanadium is a side product from refining coal, because vanadyl porphyrins are very stable (their stability is exceeded only by the nickel porphyrins).

The phase rule is a relation among the number of independent components, the number of phases, and the variance of a system in equilibrium. The independent components (or, briefly, the components) of a system are the substances that must be added to realize the system. The phases have been defined earlier (Section 1-3). Thus a system containing ice, water, and water vapor consists of three phases but only one component (water-substance), since any two of the phases can be formed from the third. The variance of the system is the number of independent ways in which the system can be varied these ways may include varying the temperature and the pressure, and also varying the composition of any solutions (gaseous, liquid, or crystalline) that exist as phases in the system. 

The important models with which we are concerned are the perfect gas, the perfect gas mixture and the ideal solution (gaseous, liquid or solid). These may be defined in either of two ways which are entirely equivalent (1) in terms of limiting experimental laws such as the gas equation and Raoult s law (2) in terms of expressions for the chemical potentials of the various components. These expressions are as follows ... 

This chapter omits two important classes of solutions gaseous mixtures, such as air, and, for the most part, ionic solutions, in which some of the constituent particles are electrically charged. Because of the special properties and great importance of ionic solutions. Chapter 12 has been reserved for them,... 

Equations (11) and (12) are based on ideal solutions (gaseous and liquid, respectively) and are, therefore, only approximately accurate for real liquid or gaseous solutions. The inadequaey of the ideal solution model to predict real solution behavior is testimony to the need for the activity coefficient.
