The greater number of bends on the fluted filter paper
translate into increased surface area and quicker filtration
. The folds also create space between the filter paper and glass funnel, allowing for displaced air to more easily exit the flask as liquid drains.
What is the advantage of using fluted filter paper instead of not folding it?
The main advantage of this method is that
it increases the speed of filtration by letting air enter the flask along its sides to bring about pressure equalization
. In addition, the fluted filter paper has a larger surface area through which the solvent can seep.
What is the primary advantage of using fluted filter paper?
The main advantage of this method is that it
increases the speed of filtration by letting air enter the flask along its sides to bring about pressure equalization
. In addition, the fluted filter paper has a larger surface area through which the solvent can seep.
What is the purpose of fluting the filter paper?
“Fluted “ filter paper (LEFT) is used
when you wish to separate a liquid and a solid, keeping the liquid and discarding the solid
. This arrangement of folds in the filter paper will allow the liquid to pass through it very quickly and give you a lot of surface area on which to collect the solid “impurity”.
What is the advantage of using fluted filter paper compared with cone shaped filter paper?
What is the advantage of fluted filter paper shown compared with cone-shaped filter paper? Fluted filter paper
has more surface area suitable for collecting solid
. After a mixture has been poured through filter paper, the (solid) component remains on top while the (liquid) flows through.
What is the difference between conical and fluted filter paper?
The conical filter method entails folding the filter paper into a cone and inserting the cone into the filter funnel. … The fluted filter paper, on the other hand,
allows air to enter the flask along
its sides to equalize pressure, thereby increasing the speed of filtration.
How is premature crystallization prevented?
Keeping the set up hot
prevents crystals from forming prematurely. Keeping the solution very hot so the solute stays dissolved, pour the solution through the funnel and filter paper assembly.
Why is the hot water used to wash the filter paper containing the activated charcoal?
Acetanilide has
a much higher solubility in hot water
than in cold water. The purified solid will not recrystallize later in the experiment if too much hot solvent is added in the beginning. Activated charcoal is then added to remove colored impurities.
What is the leftover material on the filter paper known as?
The solid particles which remain on the filter paper after the filtration is called
Residue
.
What is Whatman filter paper?
Whatman filter paper is
a cellulose paper made by using a high percentage of alpha-cellulose
. Its contents are a sign of its consistency and high quality as alpha cellulose is considered the most stable form of cellulose. Not only this, it has the highest degree of polymerization.
What should you do if you see crystals or cloudiness in the bottom of the filter flask during vacuum filtration?
The proper way to wash the crystals is to SHUT OFF the vacuum,
add a minimum amount of cold solvent
so that the crystals are barely sitting in solvent for about 5 Page 4 seconds (the solvent will not drip through quickly) and then apply the vacuum. The solvent will be sucked into the filtrate.
When using a separatory funnel you should burp the funnel What does the term burping mean quizlet?
When using a separatory funnel, you should burp the funnel. What does the term burping mean?
Opening the stopcock when the flask is inverted during mixing
.
What is the best course of action if a gravity filtration setup seems unsteady?
What is the best course of action if a gravity filtration setup seems unsteady?
Clamp the setup to a ring stand.
