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.
Is it possible to prepare a standard NaOH solution by dissolving an accurate amount of NaOH pellets in a known volume of water?
Yes, it is possible to prepare a standard NaOH solution by dissolving an accurate amount of NaOH pellets in a known volume of water. This process allows for the calculation of the concentration of the NaOH solution based on the amount of NaOH used and the volume of water.
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).
What must be done to determine the concentration of a non standard solution?
Titrate it with a primary standard
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.
What is primary standard solution?
A primary standard solution is a highly purified compound that is used as a reference material for accurately determining the concentration of another solution through titration. It is typically used in titration experiments due to its known high purity and stability.
What is standard solution in titration?
A standard solution in titration is a solution of known concentration that is used to determine the concentration of another solution. It is typically a primary standard that can be accurately weighed and dissolved to make a solution of precise concentration. Standard solutions are essential in titration to accurately measure the volume of the solution being titrated and calculate its concentration.
Suppose your laboratory instructor inadvertently gave you a sample of khp that was contaminated with nacl to standardize your naoh how would this affect the normality you calculated for your naoh sol?
Potassium acid phthalate is a common primary standard used to standardize bases. Obviously, it would depend upon how much NaCl was present, but the end result will be to reduce the amount of available H+ for the mass of KHP-NaCl mixture. That would cause you to understate the concentration of the base.
What is a secondary solution?
A solution that has been titrated against a primary standard solution.
Why is it necessary to standardize a solution of NaOH using a primary standard, such as KHP?
It is necessary to standardize a solution of NaOH using a primary standard like KHP because primary standards are highly pure and have a known exact mass. This allows for accurate and precise determination of the concentration of the NaOH solution, ensuring reliable and consistent results in experiments.
Is sodium thiosulphate solution a primary standard?
No, sodium thiosulfate solution is not typically considered a primary standard. It is commonly used as a titrant in redox titrations rather than as a primary standard due to its susceptibility to oxidation by air. Primary standards are typically pure, stable compounds that can be used to standardize solutions.
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.
