Water Specification

The Water, with the CAS registry number 7732-18-5,is also known as Deionized water;Distilled water;Purified water. It belongs to the product categories of Melamine;Mono-;Mycotoxins;NOWPak Products;saccharides);Sterols.Its EINECS number is 231-791-2. This chemical's molecular formula is H2O and molecular weight is 18.01. What's more,Its systematic name is Water.It is a colourless liquid which is used in the preparation of cell culture media, and cell suspension and washing solutions.It is a clear, odorless, tasteless liquid that is essential for most animal and plant life and is an excellent solvent for many substances.Water is miscible with many liquids, for example ethanol, in all proportions, forming a single homogeneous liquid.Water and most oils are immiscible usually forming layers according to increasing density from the top. As a gas, water vapor is completely miscible with air. Water forms an azeotrope with many other solvents. Water can be split by electrolysis into hydrogen and oxygen.
