Which term describes a solution having a very well-known concentration of solute? Select one: Primary standard Standard solution Volumetric analysis Secondary standard

Standard solution

Explanation:

In chemistry, standard solutions are solutions that contain a very well known concentration of a substance such as solutes. In other words, standard solutions contain solute concentrations that are accurately (without errors) known. They are prepared by dissolving a known mass of solute in a known volume of solvent.

Standard solutions are majorly used to determine the concentration of another solution, whose concentration is unknown. Standard solutions contain a primary standard, which possess characteristics such as high solubility, high purity etc.

ok whats the question if not i cannot you i need question and need a thing to answer
