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

What is type of volumetric analysis?
Volumetric relates with volume, mostly refers to gas adsorption. After placed your samples into a sample tube, inset adsorbate gas like N2, then your sample will adsorb the N2, finally using professional analyzer to calculate how much gas adsorbed, then will know your sample adsorpiong characteristics. For example, using V-Sorb 2800P volumetric adsorption analyzer, it can get adsorption isotherm, then will know surface area, pore size etc key data which is very important for researchers to know their samples performance.
What is a secondary solution?
A solution that has been titrated against a primary standard solution.
What is a standard solution?
A standard solution is a solution of known concentration that is used to determine the concentration of an unknown solution in a chemical analysis. It is often prepared by accurately measuring a known amount of solute and dissolving it in a known volume of solvent.
What errors can occur by preparing a solution using cold water as a solvent?
The volume of any material depends on the temperature; to prepare water solutions (titrant, standard solution, control sample, etc.) for chemical analysis the normal and general accepted temperature is 20 oC for water. Also volumetric glassware is graduated at 20 oC.
Why to use 84 microsiemens conductivity standard solution?
Standard solutions are used to check instruments and methods of analysis.
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.
Why is it advisable to prepare a slightly more concentrated solution of potassium permanganate when preparing its standard solution?
Preparing a slightly more concentrated solution of potassium permanganate for a standard solution ensures higher accuracy in the volumetric analysis. This allows for more precise measurements and reduces errors in the dilution process. Additionally, a concentrated solution is more stable and less prone to degradation over time, ensuring the standard solution remains reliable for a longer period.
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.
What is a standard solution in an acid-base titration?
It is a solution of known concentration. In acid base titrations we used KHP as the acid standard. We weighed it to 0.1 mg and made the solution up to a certain volume in a volumetric flask. We then standardized the base by titration. KHP was thus the primary standard and NaOH the secondary std.

What precise volumetric equipment is used in titrations?
In titrations, precise volumetric equipment like burettes and volumetric flasks are commonly used. Burettes are used to deliver precise volumes of titrant, while volumetric flasks are used to prepare accurate standard solutions or to collect titrated solutions for analysis.
What is a secondary standard substance?
solution that changes it's strength with the passage of time.
What is a secondary solution?
A solution that has been titrated against a primary standard solution.
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.
