Where do you get the 82.81 ml during the preparation of 1 N solution of HCl from a concentrated 37 percent HCl?

Try a gradual measuring pipet max. 100 mL from which you'll get 83 (+/- 1) mL.
More accurate then this is not easily done and besides that it's also not usefull: the given concentrated 37% is also accurate between 36% - 38%, so you'll never get an exact 1.00 N HCl.

If 2 percent glucose solution and 5 percent glucose solution are separated by a semipermiable menbrane flows from the 2 percent glucose solution to the 5 percent glucose solution?
Yes, during process of osmoses the solvent from higher concentration to lower concentration moves through semipermeable membrane, the 2% solution has lower concentration of solute therefore higher concentration of solvent.
What happens during the process of osmosis?
Osmosis is the random movement of water particles through a partialy permiable membrane from a higher concentration to a lower concentrated solution.
What would happen if you were to take a saturated solution at a certain temperature and cool it slowly?
the concentration of this solution is going to reduce.< Lets assume that the solution is comprised of water and salt> Then the water at a certain temperature begins to evaporate unlike the salt. at the end of the process, yes we agree that the solution has finally come to a room temperature, but concentration was lost during cooling. I mean that the solution becomes less concentrated
which of the following is not a use for the air-water syringe in four-handed dentistry?
A.
What happened if some solution splashes out during the titration of NaOH?
If some solution splashes out during the titration of NaOH, the volume at the end point will be wrong.
What is the difference between solution and concentrared solution?
A solution is a solute dissolved in a solvent. A concentrated solution is all the solute that be dissolved in a solvent at normal temperature. A super-concentrated solution is all the solute that can be dissolved in a solution after mixing in the solute during high temperature / pressure. The concentration after cooling to normal temperature / pressure is greater than a regular concentrated solution.
Why is Ammonia solution added while preparing EDTA solution?
ammonia solution is added during the preparation of EDTA solution to increase the rate of dissolution of its disodium salt.
What controls the direction of water movement during osmosis?
According to the Oxford English Dictionary, osmosis is defined as "a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one" (OED 2013). The greater mass present in the higher concentrated solution of the solvent causes the water molecule to pass through the sempermeable membrane until the water concentration of water with concentrated solution are balanced on both sides.
If 2 percent glucose solution and 5 percent glucose solution are separated by a semipermiable menbrane flows from the 2 percent glucose solution to the 5 percent glucose solution?
Yes, during process of osmoses the solvent from higher concentration to lower concentration moves through semipermeable membrane, the 2% solution has lower concentration of solute therefore higher concentration of solvent.
What happens during the process of osmosis?
Osmosis is the random movement of water particles through a partialy permiable membrane from a higher concentration to a lower concentrated solution.
Is the preparation of sugar solution physical change?
Yes. Both the sugar and the water (or other solvent) remain the same chemicals. Since no chemical change occurs during creation of the solution, it is a physical change.
Why do you use iodine solution during the preparation of slide of onion peel?
So that you can observe different characteristics of the cell clearer such as the nucleus, vacuoles or other membrane bound organelles.
Why is 2 4 DiNitroPhenylHydrazone washed with methanol when prepared?
2,4-dinitrohydrazine used during the preparation is a base and may form hydrazonium ion in solution, for the removal of this methanol is used.
What happened during the diffusion?
the particles tend to move from an area where they are more concentrated to an area where they are less concentrated.
