Is it possible to prepare a standard NaOH solution by dissolving an accurate amount of NaOH pellets in a known volume of water?
you can't make a primay standard solution with NaOh.as NaOh is said to be a secondary standard you have to establish the normality using some primary standard acids.
What is a secondary solution?
A solution that has been titrated against a primary standard solution.
What is primary standard?
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).
How to prepare a standard solution of potassium iodate?
it is primary standard........ but before making solution dry it at 120. C
Difference between primary standard solution and a secondary standard solution in acid-base titration?
primary standard solution is prepared by direct measurements of the mass of solute and the volume of solution.whereas, a secondary standard solution is a solution whose concentration can't be determined directly from weight of solute and volume of solution, the concentration must be determined by analysis of the solution itself.
What is primary standard solution?
A primary standard is a reagent that is extremely pure, stable, has no waters of hydration, and has a high molecular weight.
What must be done to determine the concentration of a non standard solution?
Titrate it with a primary standard
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 the types of standard solutions?
there are two types of standard solution 1 primary 2 secondary
Standardization of hcl solution with primary standard na2co3 solution?
solution containig (3.3)gm na2co3 .h2o in (15ml)
Is sodium chloride solution a standard solution?
Sodium chloride is a crystalline solid but can be dissolved in water to form a solution.
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
