Standard Solution
A Standard Solution (pronunciation: /ˈstandərd səˈlo͞oSH(ə)n/) is a solution whose concentration is accurately known. It is typically used in titrations to determine the concentration of an unknown substance.
Etymology
The term "Standard Solution" is derived from the English words "standard" and "solution". The word "standard" comes from the Old French estendard, meaning "a rallying place or flag to muster under", and the Latin solutio, meaning "a loosening or dissolving".
Related Terms
- Titration: A method or process of determining the concentration of a dissolved substance in terms of the smallest amount of a reagent of known concentration required to bring about a given effect in reaction with a known volume of the test solution.
- Concentration: The measure of how much of a given substance there is mixed with another substance.
- Solution: A type of homogeneous mixture that is made up of two or more substances.
- Reagent: A substance or compound added to a system to cause a chemical reaction or test if a reaction occurs.
Usage
In Chemistry, a standard solution is prepared by dissolving a known weight of solute in a solution to make a specific volume. It is used in analytical chemistry to determine the amount of a chemical species. In biochemistry, it is used in titration to determine the concentrations of certain components of a solution.
