Why would NaOH not be used as a primary standard in the standardization of HCl with Borax?
Sodium hydoxide cannot be used as a primary standard because of its hygroscopic properties as a solid. Because it is so prone to absorbing water, it is impossible to accurately measure the mass of a solid sample, so instead it must be put into solution and tirated with a known acidic solution, such as HCl. This makes it a secondary standard as opposed to a primary standard. By. Kuatsienu Divine
What is the primary standard apparatus in chemistry?
we use primary standard apparatus in chemistry lab to find accurate resultthe examples of primary standard apparatus arepippetteburreteVolumetric Flask
Is hcl praimary standard or secondary standard?
HCl is not used as a primary standard
What is the primary standard used in this experiment .define a primary standard?
It is primary standard is a substance that has a known high digree of purity ,reatively large molar mass ,is nonhygroscopic and reacts in a predic table way.
Is hcl a primary standard or a secoundary standard?
HCl is a gas which is dissolved in water to form the solution the concentration expressed is very approximate so its not a primary standard.
What are three reasons why borax is a good primary standard?
i need ideas to complete my assignment
Why is borax a good standard?
The best standard is borax from NIST- code 187e.
What is the theory of standardization of hydrochloric acid with Borax?
Borax can be used as a primary standard because it does not decompose in normal storage conditions. The salt will dissociate in water and the anion will be hydrolyzed. This leaves hydroxide ions to be titrated with the hydrochloric acid.

Why iodine is not directly employed as the primary standard?
In order for a substance to be a primary standard it must be able to dissolve in water. Since iodine is unable to do this it cannot be used as 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.
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.
