Hi there!
It is necessary to rinse the inside of an Erlenmeyer flask with deionized water periodically to wash the flask without adding ions which could affect the titration.
If you wash an Erlenmeyer flask with regular tap water, you are adding ions, like sodium or chlorine, which could make you miss the equivalence point by only tenths of mL (that's a big difference when titrating). This is why when washing you use deionized water to clean the flask while ensuring that your titration is accurate.
Have a good day!
Answer:
Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.
Explanation:
Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.
Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.
