Why must the stem of the funnel touch the inside surface of the collecting beaker during filtration?
it's done to minimize the mixing of air into the filtered solution. By touching the stem to the collecting beaker, the solution flows into the beaker smoothly rather than splashing into it.
What are two substances that do not leave the glomerulus during filtration?
RBC's and mostly all proteins
What process cause salts and other wastes to move out of blood during filtration?
Liver
Why it is important to minimize the evaporation during the filtration of hot solution?
Because some of the compounds of the solution can disappear in the air by evaporation.To avoid recrystallization in the funnel. And rapid crystallization will occur if there is maximum evaporation.
What is meant by the terms decantation and filtration?
The larger and heavier solid particles settle down leaving the clear liquid above it. ... At the same time, during decantation, there is a chance of the particles mixing back in the liquid. The filtration technique can be used to overcome this as well. Thus, filtration is better than sedimentation and decantation.
What is an pear-shaped flask and how is it used?
It is used in setup with filtration and distillation happening at the same time. Anti bumping granules and the solution are place in it to avoid solution being "bumped out" of the flask during the filtration and distillation process
Is running water through a filter considered a chemical change?
No, This is a process to obtain a solid from an aqueous solution. No chemical process is taking place during filtration.
How are soluble impurities removed during a recrystallization?
Soluble impurities are removed by a process of vacuum filtration
What rhymes with reccuring?
during blurring stirring referring

What is the function of stirring rods?
to mix chemicals during a lab.
What rhymes with transferring?

What is the function of glass stirring rod?
to mix chemicals during a lab.
Is urine formed when absorption and reabsorption happen during blood filtration?
This is true.
Why does the molecule of starch stay back during filtration?
because they are fatter than the others
