Question

What is a standard solution?

Answer 1

Hint :We know that a solution is a homogeneous mixture of two or more than two substances whose particle size is \[0.1nm\text{ }-1nm.\] Homogeneous means that the components of the mixture form a single phase. Solutions consist of -Solute and Solvent

Complete Step By Step Answer:
A solution containing a specifically defined quantity or substance is a typical solution in analytical chemistry. To achieve a given amount, a specified weight of solution is dissolved. It is made of a standard material, such as a primary standard. Generic solutions, such as titration solutions, are used to determine quantities of certain compounds. Standard solutions concentrations usually measured in units of moles per litre, moles per cubic decimeter.
Standard solutions are solutions that have a defined and correct quantity of the material or product (i.e. concentration). These solutions are often used to help identify and determine the concentration of an unknown substance. Let's claim an uncertain material when testing it, that we want all the tests to be as reliable as possible. As these solutions contain precise chemical component concentrations, in the determination of unknown concentrations of substances will be improved.

Note :
Remember that there are two types of standard solution. First one is the primary standard solution and second one is the secondary standard solution. In primary standard solution, the solutions are pure and stable and the properties of these solutions does not change while secondary standard solutions are those solutions which are specified task by mixing solute in small quantity and solvent in large quantity.
