There are three types of solutions that can occur in your body based on solute concentration: isotonic, hypotonic, and hypertonic. WebIn standard solutions, we use standard substances and know their concentrations accurately. Traditionally, we label standard solutions either as primary standards or secondary standards. A secondary standard solution is standardized through a primary standard. Secondary standards can be used for a variety of analytical experiments.
