Final answer:
Many types of clinical laboratory analyses, such as potentiometry and polarography, are based on chemical methods and electrochemical methodologies. Chemical methods use stoichiometry of chemical reactions for quantitative analysis, while electrochemical methods measure potential and current for analysis.
Step-by-step explanation:
Many types of analyses used in the clinical laboratory, such as potentiometry, amperometry, coulometry, and polarography, are based on chemical methods and electrochemical methodologies. In chemical methods, the stoichiometry of chemical reactions serves as the basis for quantitative chemical analysis. Titrations involve measuring the volume of a titrant solution required to react completely with a sample solution, and gravimetric analysis involves separating the analyte based on its mass.
In electrochemical methodologies, potentiometry is used to monitor the change in potential while adding the titrant to the titrand. Amperometry involves measuring the current produced during a reaction, and coulometry and polarography measure the amount of electricity required to perform the analysis.
Overall, these analyses are based on the principles of chemical reactions, stoichiometry, and electrochemistry.
