What type of filter paper does the company called Whatman sell?
Whatman are world leaders in the sale of laboratory grade filter papers. They pride themselves on the quality of their filter paper and the reproducibility achieved when using their filter papers.
Where available filter paper for test petrol quality?
This filter paper is not so important, you can use different types. An example is Whatman grade 2 filter paper; see the link below.
What is chromatography paper called?
Chromatography paper is also called filter paper because it is commonly used to separate mixtures of substances based on their different polarities as they move through the paper.
How do you determine pore size whatman filter paper?
Pore size in Whatman filter paper is typically determined using a bubble point test, which measures the pressure required for gas bubbles to pass through the pores. Another method is the mercury intrusion porosimetry, where mercury is forced into the pores to measure their size. Both methods provide valuable information on the pore size distribution in the filter paper.
Paper used in chemistry experiments?
Filter paper and litmus paper are commonly used in chemistry experiments for various purposes such as filtering solutions and testing for acidity or alkalinity. Additionally, weighing paper is used to accurately measure and transfer solid substances in the laboratory.

Is dialysis possible using whatman filter paper?
No, dialysis is typically performed using a specialized dialysis membrane that allows for the separation of molecules based on size. Whatman filter paper is not designed for dialysis as it lacks the necessary properties to effectively separate molecules based on size through the process of diffusion.

Chromatography paper is also called filter paper because it is commonly used to separate mixtures of substances based on their different polarities as they move through the paper.
Molecular size of lauric acidwhat size Whatman filter paper for filtering lauric acid?
The molecular size of lauric acid is approximately 200 g/mol. A Whatman filter paper with a pore size of 2-4 microns would be suitable for filtering lauric acid, as it can effectively trap particles of this size during the filtration process.
What do you mean by what-man filter paper no 1?
Whatman filter paper No. 1 is a type of filter paper that is commonly used for routine filtration applications in laboratories. It has a medium flow rate and particle retention, making it suitable for clarifying liquids and removing solid particles from solutions. The number "1" indicates the grade of the filter paper, with No. 1 being one of the most common grades used in scientific experiments.
What is the purpose of using a chemistry filter paper in laboratory experiments?
A chemistry filter paper is used in laboratory experiments to separate solid particles from liquids, allowing for the purification and analysis of substances.

Was the Domesday Book written on Whatman paper?
No, the Domesday Book was not written on Whatman paper. The Domesday Book, which was a comprehensive survey of land and property in England, was written on parchment. Whatman paper, on the other hand, was developed in the 18th century and was not in use during the time the Domesday Book was compiled in the 11th century.
What is the example of paper chromatography?
See the link below for details. Whatman is a source of papers for chromatography.
Why is filter paper used in chromatography?
Filter paper is used in chromatography because it is porous and allows the solvent to travel through it by capillary action. This helps separate the components of a mixture based on their solubility and affinity for the stationary phase. The filter paper also provides a large surface area for the separation to occur effectively.
