Answer:
1.
Word: Reagent
Definition: a substance or mixture for use in chemical analysis or other reactions.
Application: There are three main applications that this reagent is used in: Quantitative organic analysis, where the Tollens reagent is used to differentiate between aldehydes and ketones Anatomic pathology, where it’s used to detect chromaffins, melanin, argentaffin, and lipofuscin in histology (i.e. the study of tissue)
2. Word: Tollen's Reagent
Definition: The Tollens Reagent is named after Bernhard Tollens, A German chemist who discovered this reagent and its uses. Tollens reagent is a solution of silver nitrate (AgNO 3) and Ammonia (NH 3). Tollens Reagent Preparation. Since Tollens Reagent has a relatively short shelf life, the reagent is not commercially sold.
Application: Aldehydes are easily oxidised to carboxylic acids but ketones are not. Aldehydes
are oxidised not only by the same reagents, which oxidizes primary and secondary alcohols
(like acidified KMnO4, K2Cr2O7) but also by mild oxidising agents like Tollen’s reagent, Fehling’s Detail Explanation and Benedict’s Detail Explanation . Aldehydes are very easily oxidised and thus are very powerful reducing agents.
3. Word: Aseptic Technique
Definition: Aseptic technique means using practices and procedures to prevent contamination from pathogens. It involves applying the strictest rules to minimize the risk of infection. Healthcare workers use aseptic technique in surgery rooms, clinics, outpatient care centers, and other health care settings.
Application: Aseptic technique is most strictly applied in the operating room because of the direct and often extensive disruption of skin and underlying tissue. Aseptic technique helps to prevent or minimize postoperative infection. PREOPERATIVE PRACTICES AND PROCEDURES.
4. Word: Microbiological Media
Definition: Microbiological media is used in testing for microbial limits, sterility, antimicrobial effectiveness, and bioburden and is critical in assessing the quality of raw materials, process waters and compressed gases, intermediate and finished product, as well as equipment and facility cleaning validation.
Application: Microbiological media is used in testing for microbial limits, sterility, antimicrobial effectiveness, and bioburden and is critical in assessing the quality of raw materials, process waters and compressed gases, intermediate and finished product
5. Word: Selective Media
Definition: Selective media generally selects for the growth of a desired organism, stopping the growth of or altogether killing non-desired organisms. Differential media takes advantage of biochemical properties of target organisms, often leading to a visible change when growth of target organisms are present.
Application: Selective and differential media are used to isolate or identify particularorganisms. Selective media allow certain types of organisms to grow, and inhibitthe growth of other organisms. The selectivity is accomplished in several ways.
