Question

why primary standard subatances are used to make standard solutions​

Answer 1

$\huge \dag \: { \boxed{ \underline{ \sf{ \pink{Answer}}}}}$

• Primary standards are typically used in titration to determine an unknown concentration and in other analytical chemistry techniques. ... The reaction confirms that the solution is at a specific concentration. Primary standards are often used to make standard solutions, solutions with a precisely known concentration.

Answer 2

Answer:

Primary standards are typically used in titration to determine an unknown concentration and in other analytical chemistry techniques. The reaction confirms that the solution is at a specific concentration. Primary standards are often used to make standard solutions, solutions with a precisely known concentration.
