FAQ
Frequently Asked Questions
Typically yes, in chemistry and biology. However, in some contexts, 'stock' can refer to concentrated solid mixtures (e.g., powder stocks for media), but the term 'stock solution' specifies a liquid form.
It is highly specialised. Figurative use (e.g., 'a stock solution of plot ideas') is possible but very rare and considered a deliberate technical metaphor.
A stock solution is simply a concentrated solution kept in storage. A standard solution is a solution of precisely known concentration, used in titrations or calibrations. A stock solution can become a standard solution if its concentration is certified.
Follow the specific material safety data sheet (MSDS/SDS). Common practices include storage in labelled, airtight containers, often at low temperatures (e.g., 4°C or -20°C) to preserve stability, and protected from light if necessary.
