Solution

In chemistry, a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent. The solution more or less takes on the characteristics of the solvent including its phase, and the solvent is commonly the major fraction of the mixture. The concentration of a solute in a solution is a measure of how much of that solute is dissolved in the solvent, with regard to how much solvent is present.

Characteristics

Types

Homogeneous means that the components of the mixture form a single phase. The properties of the mixture (such as concentration, temperature, and density) can be uniformly distributed through the volume but only in absence of diffusion phenomena or after their completion. Usually, the substance present in the greatest amount is considered the solvent. Solvents can be gases, liquids or solids. One or more components present in the solution other than the solvent are called solutes. The solution has the same physical state as the solvent.

Solution (band)

Solution were a Dutch progressive rock band that existed from 1970 to 1983, during which time they released six studio albums and one live album. They incorporated jazz, rock, pop and soul influences, becoming more commercial on their fifth and sixth albums.

History

Their first eponymous LP comprised mainly instrumental pieces, complex yet repetitive in structure, with bassist Peter van der Sande singing on one track. He was succeeded by Guus Willemse around the time of its release, and immediately the band began recording more vocal songs; three of the tracks on second album Divergence featured lyrics.

The third album Cordon Bleu (1975) was released on Elton John's own label named The Rocket Record Company, as was its follow-up Fully Interlocking (1977). Both albums were produced by John's producer Gus Dudgeon, and featured a crisper sound and more concise songwriting.

Despite some criticism for a more commercial direction, the next two albums, ...It's Only Just Begun... (1980) and Runaway (1982) continued this trend. The two title tracks from these albums became hit singles in Europe.
