Solutes bound

If the solubility of either component in the other is unlimited ( free miscibility, as with alcohol and water), there may be an infinite number of solutions, lying between the two pure substances as limiting cases. The solubility may be limited in one or both directions. Thus, water and salt form a series of solutions extending indefinitely towards pure water as one limit, but bounded by saturated salt solution as the other limit water and ether form a continuous series of solutions bounded on one side by a saturated solution of ether in water, and on the other side by a saturated solution of water in ether. In the region of continuous miscibility all the properties of the solution vary... 

Another process for the separation of toxic chemicals from waste streams species involves adsorption from solution onto particles, followed by sedimentation to remove the toxic-laden particles. Solutes bound to the surface of... 

The designer starts with the set of all possible solutions bounded by the external constraints, and by a process of progressive evaluation and selection, narrows down the range of candidates to find the best design for the purpose. 

In the case of a solution bounded by a semi-permeable membrane, the pressure which must be applied to drive the solvent molecules through the membrane is termed the osmotic pressure. See Osmosis and Molecular Weight.

In this rapidly developing field the crystal stmcture of the specific donor-acceptor pair dominates the solution bound redox potentials which are discussed here. 

For separation by adsorption, adsorption capacity is often the most important parameter because it determines how much adsorbent is required to accomplish a certain task. For the adsorption of a variety of antibiotics, steroids, and hormons, the adsorption isotherm relating the amount of solute bound to solid and that in solvent can be described by the empirical Freundlich equation. 

When a nucleic acid interacts with cations in aqueous solution, bound states form in the interfacial region of the macromolecule [10], These states are classified either as site bound or diffusely bound [9, 11-14], If the translational energy of the ions is unable to overcome the electrostatic forces between the ions and the nucleic acid, then the ions are viewed as trapped in a volume encasing the surface of the nucleic acid. These ions are site bound [9, 11, 13, 14]. 

Addition of a solute bound to the interface layer increases the surface area while keeping the overall volume constant. This results in a reduction in the size of the water pool. 

Table II gives binding constants and partition coefficient values (P) calculated by the NLLSQ program using reported capacity factors for solutes bound to micelles. These values were determined on two different LC columns. One to one equations were used to obtain the binding constants (Equation 1). This table shows the ability of this particular NLLSQ routine to perform linear least square approximations. NLLSQ programs usually are less accurate at this. The mobile phase in this study was composed of solutions of sodium dodecylsufate (SDS). These binding constants were converted to partition coefficients by Equation 4.

Another concern is that, for a 9-coordinate lanthanide ion in aqueous solution bound to a single tridentate DPA ligand, the six coordinated water molecules will strongly quench the luminescence (92). To eliminate the potential for solvent quenching and improve the sensitivity of the assay, we explored the use of a hexadentate ancillary ligand to encapsulate the Tb ion and exclude solvent from the coordination sphere without impeding dipicolinate chelation. 

Consider a semi-infinite expanse of ionic solution, bounded on one side by a planar solid surface where o is specified. Because of the condition of overall electroneutrality, the surface charge plus the bulk charge must sum to zero. From this and the Poisson and Boltzmann equations, one can derive (Israelachvili 1992)...

Elute the analyte from the disk with the appropriate solvent. Typically, ethyl acetate will work quite well for removing solutes bound by a reversed-phase mechanism. The typical generic method, described in Chapter 3, will work well. For a 47-mm disk, 10 mL of elution solvent in two 5-mL aliquots will give good elution recovery from a C-18 disk for most compounds. A slower flow rate for elution will give better recoveries, and it is a good idea to soak the disk for several minutes with elution solvent. This step allows the solvent to wet the disk well and to give effective elution recovery. 

In acid and base reactions, hydrogen ions are added to molecules or removed from them. A hydrogen ion, often written as H, corresponds to a bare proton. In fact, hydrogen ions exist in solution bound to water molecules, thus forming what are known as hydronium ions, HjO. For simplicity, we will continue to write but we should keep in mind that is shorthand for the actual species present.
