What is a solution? What is a standard solution? In fact, many people often confuse the two, generally speaking, the solution refers to a mixture of many or at least two substances, while the standard solution is a reagent solution with an exact known concentration, but the standard solution is a generic solution, although there is a clear difference between the two. The following is a small edition of Bolinda to give you a detailed introduction to the difference between standard solution and solution.

Difference between standard solution and solution:

A solution is a uniform, stable mixture of at least two substances, and the dispersed substance (solute) is dispersed in molecules or smaller particles in another substance (solvent). At room temperature, substances have three states: solid, liquid and gas.

The uniformity of the solution includes the same density, composition, and properties. In addition, the solution is also divided into saturated and unsaturated solutions.

Standard solution is a titration solution commonly used in volumetric analysis to measure the content of the substance to be measured. That's how we find the concentration of the unknown solution. In other analytical methods, the standard solution is used to draw working curves or as a calculation standard.

Some standard solutions are so unstable that they are difficult to prepare and use that they cannot be used.

Such standard solutions include hydrogen sulfide (H2S), chlorine dioxide (ClO2), dissolved oxygen (DO), and ozone (O3). The liquid chlorine standard solution can only be formulated into a high concentration solution, so it must be diluted by adding high purity water and using glassware that does not consume liquid chlorine.

The above content is the introduction of the difference between the standard solution and the solution, some solutions purity can not reach or easy to absorb water, can only roughly weigh or measure a certain amount of substance or solution, prepared into a solution close to the required concentration. Since their exact concentration is unknown, their exact concentration must be determined with a reference substance or a standard titration solution of another substance.
