What laundry soap is considered a substitute for borax?
It is all borax unless it is considered with scent ..............
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
Why Mohr's salt is considered a primary standard?
The Mohr salt is more stable to oxidation of Fe2+ to Fe3+.
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 EDTA considered as a primary standard?
No. Chemical compounds have to fulfill a number of requirements before they can be classified and used as a primary standard: A primary standard in chemistry is a reliable, readily quantified substance. Features of a primary standard include: 1. High purity 2. Stability (low reactivity) 3. Low hygroscopicity and efflorescence 4. High solubility (if used in titration) 5. High equivalent weight 6. Non-toxicity 7. Ready and cheap availability Edta and particularly the sodium salts of EDTA which are frequently used do not fulfill the first requirement. Therefore the solution of EDTA has to be standardised against a known and accepted primary standard.
What are three reasons why borax is a good primary standard?

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.

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.
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
