A measure of the acidity of the solution
Immunoassay interference refers to factors that can impact the accuracy of immunoassay test results by causing false positive or false negative outcomes. These interferences can be due to the presence of substances in the sample that can cross-react with the assay components, leading to incorrect measurements. It is important to identify and minimize immunoassay interferences to ensure the reliability of test results.
To measure the total nutrients in a solution.
The pH is a measure of the acidity/alkalinity of a solution.
Titration is a laboratory method used to determine the concentration of a solution by reacting it with a solution of known concentration. It is commonly used to measure the concentration of acids and bases, as well as other substances in solution.
The measure of the H+ concentration is the pH.
The most commonly used measure of concentration for an aqueous solution is molarity, which is the number of moles of solute per liter of solution.
The acidity percentage of the solution is the measure of how acidic it is. It is typically expressed as a percentage of the total solution.

A hydrometer or a refractometer can be used to measure the salinity level of a saline solution. These tools are specifically designed to measure the concentration of dissolved salts in a liquid.
