Primary standards have some peculiar properties

  1. They are nonsensitive to atmospheric oxygen
  2. They have known formula and molecular weight
  3. They are usually high molecular weight compounds
  4. They have a constant concentration /uniform composition for a long period of time
  5. They are powerful reactants

Secondary standards are

  1. Influenced by atmosphere/environment
  2. Concentration change over time
  3. Usually powerful reactants
  4. Usually cheap & easy to use

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.

0.1N Sodium Thiosulphate is primary or secondary solutions?

it is a secondary solution because it can change its concentration by absorbing moisture....


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.


Is hcl praimary standard or secondary standard?

Hydrochloric acid (HCl) is considered a primary standard because it is a highly pure compound that can be used directly to prepare standard solutions for titrations and other analytical procedures without the need for standardization.


Is West's Analysis of American Law primary or secondary authority?

West's Analysis of American Law is considered a secondary authority. It provides commentary and analysis on legal topics rather than directly interpreting primary sources of law.


Primary topics are often analysis or secondary sources?

Primary topics are often secondary sources. Secondary sources analyze in review or summarize information.


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 Secondary standard solution in volumetric analysis with example?

Primary standard is a chemical entity available with highest purity and stability with high molecular weight. e.g. KHP, NaCl, Calcium salt used in standardisation of volumetric solution. Secondary standards are compounds used in analysis after evaluation against primary standards. e.g.- NaOH VS, Sodium thiosulphate VS
