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.
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.
How many types of standard solution?
ANSWER:- There are nine types of solution:- (1). Gas of Gas. (2).Gas of Liquid. (3).Gas of Solid. (4).Liquid of Gas. (5).Liquid of Liquid. (6).Liquid of Solid. (7).Solid of Solid. (8).Solid of Liquid. (9).Solid of Gas.
Why EDTA ia secondary standard?
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.

Why primary and secondary standard solutions are needed in analysis.?
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 )
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.
What is germanys standard of living?
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.
What is Primary demand and secondary demand?
primary and secondary demand
Difference between primary server and secondary server?
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.
A transformer has 20 primary windings and 100 secondary windings If the secondary voltage is 25 V find the primary voltage?
Voltage on primary/Primary turns = Voltage on secondary/Secondary turns
