Solvent Violet 13, also known as D&C Violet No.2, oil violet, Solvent Blue 90, Alizarine Violet 3B, Alizurol Purple, Duranol Brilliant Violet TG, Ahcoquinone Blue IR base, Quinizarin Blue, Disperse Blue 72, and C.I. 60725, is a synthetic anthraquinone dye with bright bluish violet hue. It is a solid insoluble in water and soluble in acetone ...
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
Negative solvatochromism corresponds to a hypsochromic shift (or blue shift) with increasing solvent polarity. An examples of negative solvatochromism is provided by 4-(4 ′-hydroxystyryl)-N-methylpyridinium iodide, which is red in 1-propanol, orange in methanol, and yellow in water.

This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, crops, or wood. Water content is used in a wide range of scientific and technical areas, and is expressed as a ratio, which can range from 0 (completely dry) to the value of the materials' porosity at saturation.
Azo violet (Magneson I; [1] p-nitrobenzeneazoresorcinol) is an azo compound with the chemical formula C 12 H 9 N 3 O 4. It is used commercially as a violet dye and experimentally as a pH indicator, appearing yellow below pH 11, and violet above pH 13. [2] It also turns deep blue in the presence of magnesium salt in a slightly alkaline, or basic ...
A typical vapor phase osmometer consists of: (1) two thermistors, one with a polymer-solvent solution droplet adhered to it and another with a pure solvent droplet adhered to it; (2) a thermostatted chamber with an interior saturated with solvent vapor; (3) a liquid solvent vessel in the chamber; and (4) an electric circuit to measure the bridge output imbalance difference between the two ...
