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.
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.
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.
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.

EDTA is considered a secondary standard because its purity needs to be verified by titration with a primary standard solution to determine its exact concentration. This is due to the fact that EDTA is hygroscopic and its concentration can vary due to absorption of moisture from the atmosphere.

The following colours are defined on a standard 12 colour wheel: - Red (primary) - - - Red-Biolet (tertiary) - - Violet (secondary) - - - Violet-Blue (tertiary) - Blue (primary) - - - Blue-Green (tertiary) - - Green (secondary) - - - Green-Yellow (tertiary) - Yellow (primary) - - - Yellow-Orange (tertiary) - - Orange (secondary) - - - Orange-Red (tertiary)

Primary standards have some peculiar propertiesThey are nonsensitive to atmospheric oxygenThey have known formula and molecular weightThey are usually high molecular weight compoundsThey have a constant concentration /uniform composition for a long period of timeThey are powerful reactantsSecondary standards areInfluenced by atmosphere/environmentConcentration change over timeUsually powerful reactantsUsually cheap & easy to useZeryawkal Ergetie(Msc in pharmaceutical Analysis )
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.
The Germans have the same standard of living as the Americans have in the United States. They may have better primary and secondary education than in the USA.
primary and secondary demand
Primary Means, it is individual there is no dependence, But Secondary will allays depends on Primary, If you want to do Secondary, you should complete primary first, There is no precondition to primary, but for Secondary Primary is the Precondition, first you should do primary, then only you are able to do secondary.
Voltage on primary/Primary turns = Voltage on secondary/Secondary turns
