A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
Making a saline water solution by dissolving table salt in water.The salt is the solute and the water the solvent. In chemistry, a solution is defined by IUPAC as "A liquid or solid phase containing more than one substance, when for convenience one (or more) substance, which is called the solvent, is treated differently from the other substances, which are called solutes.
In analytical chemistry, a standard solution (titrant or titrator) is a solution containing an accurately known concentration.Standard solutions are generally prepared by dissolving a solute of known mass into a solvent to a precise volume, or by diluting a solution of known concentration with more solvent.

The following outline acts as an overview of and topical guide to chemistry: . Chemistry is the science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions.
In solutions, solutes will not settle out after any period of time and they cannot be removed by physical methods, such as a filter or centrifuge. [12] As a homogeneous mixture, a solution has one phase (solid, liquid, or gas), although the phase of the solute and solvent may initially have been different (e.g., salt water).
Brady Tkachuk scored 21 seconds into overtime, lifting Ottawa to a 3-2 victory over the Bruins on Saturday night and handing a win to Linus Ullmark in his return to Boston. The 31-year-old Ullmark ...
Friendster was a social networking service originally based in Mountain View, California, founded by Jonathan Abrams and launched in March 2003. [2] [3] Before Friendster was redesigned, the service allowed users to contact other members, maintain those contacts, and share online content and media with those contacts. [4]
