Question

Are all standard solution primary standard solution???

Answer 1

Explanation:

In analytical chemistry, a standard solution is a solution containing a precisely known concentration of an element or a substance. ... It is prepared using a standard substance, such as a primary standard. Standard solutions are used to determine the concentrations of other substances, such as solutions in titration.

Answer 2

Answer:

No, all the standard solutions are not primary standard solutions.

Explanation:

In analytical chemistry, a standard solution can be defined as the solution containing a precise and exact known concentration of an element or a substance. It is prepared only using standard substances. Standard solutions are used in titration in order to determine the concentrations of other substances, such as solutions.

But many standard solutions are only secondary standard solutions because their concentration changes with time and also it is impossible to produce the exact concentration every time.

So, it can be concluded that all the standard solutions are not primary standard solutions.
