A primary standard solution is generally a solution prepared and certified by an authorized and specialized institution (for example: NIST - National Institute for Standards and Technology).
What else can I help you with?
Is k2cro4 a primary or secondary standard and why?
K2CrO4 is a secondary standard. This is because it is not directly titrated against a primary standard but rather is standardized by titration against a primary standard, such as sodium thiosulfate in iodometric titrations.
A solid acid of high purity that can be accurately weighed and directly determined is called?
A primary Standard
What is primary standard substance?
A primary standard substance is referred to a reagent which is pure. This is a substance that can be weighed easily due to its purity.
Is hcl a primary standard or a secoundary standard?
HCl is not typically used as a primary standard because it is difficult to obtain in a pure solid form. Instead, it is usually standardized against a primary standard such as potassium hydrogen phthalate (KHP) or sodium carbonate.
What is aprimary standard?
Primary standard can be defined in metrology, as a standard that is accurate enough that it is not calibrated by or subordinate to the other standards. Primary standards are used to calibrate other standards.
What are the types of standard solutions?
The two main types of standard solutions are primary standard solutions, which are highly pure and stable substances that can be used to make precise titrations, and secondary standard solutions, which are solutions prepared using a primary standard solution as a reference for their concentration.
Is borax a primary standard?
No, borax is not considered a primary standard. Primary standards are highly pure reagents that can be used to standardize solutions for volumetric analysis, while borax is typically used as a secondary standard for acid-base titrations.
Why iodine is not directly employed as the primary standard?
Iodine is not directly employed as a primary standard because it is less stable in solution compared to other primary standards like potassium dichromate or potassium permanganate. Additionally, iodine is sensitive to light and air, leading to potential degradation and affecting its accuracy as a primary standard.
What viscosity is used in the primary?
Either full synthetic or standard primary oil.
advantage of KIO3 as a primary standard?
what is the advantage of potassium iodate as aprimary standard
What must be done to determine the concentration of a non standard solution?
Titrate it with a primary standard
What is the primary standard used in this experiment .define a primary standard?
The primary standard used in an experiment is typically a highly pure compound that can be used to determine the concentration of another substance through titration or other analytical methods. A primary standard is defined as a substance of known purity that can be accurately weighed out to prepare a solution with a precisely known concentration.
