Why rinse the burette with distilled water?
To remove any trace of other chemicals that may still be in the burette.
What is the purpose rinsing the burette with distilled water during titration?
Burette is used to measure the accurate value of taking products and we will calculate the lower minuscus and upper minucus of the burrete that's why we using the burette
What happens when a drop remains hanging from the tip of the burette after the solution has been added to the flask?
If there are any drops still hanging on the burette, they should be washed into the flask with distilled water.
When water is in a container the surface of the water is curved this curve is call?
Meniscus is the curve at the surface of a liquid in a cylinder. It is caused by the adhesive and cohesive properties of water molecules. (Meniscus was incorrectly spelled in an earlier answer as "miniscus.")
Why is it necessary to rinse the burette with sodium hydroxide before you completely fill it up?
Before a burette is used, it needs to be cleaned. During the cleaning process, usually, water is introduced into the burette. Be the water clean or not, if the burette is then used without rinsing it with the solution that it is going to be filled with, the result of that analytical exercise will not be precise and accurate. The reason is that water residue in the burette would dillute the solution when it's filled in the burette which would make it impossible to determine the exact concentration of the solution moved by the burette. By rinsing and re-rinsing the burette several times with the solution it is going to be filled with, residue water from the cleaning process would be successfully removed from the burette as are other leftover substances from the cleaning process. This practice is quite important as basic analytical technique.
When water is in a container the surface of water is curved. this curve is called?
convex
When water is in a container and the water is curved What is the curve called?
This is called the meniscus. The meniscus is caused by the high surface tension of water.
Which property of water causes a curved surface?
Adhesion is the property of water causes the curved surface
When water is in a container the surface of the water is curved. this curve is called the?
The meniscus - the upward curve of a liquid in a narrow vessel.
Why was the surface of a Roman road curved?
The surface of a Roman road was curved to make water run off.
When water is in a container the surface of the water is curved is called what?

What do you call the curved upper surface of water that commonly appears when using graduated cylinders?
This is called meniscus.
Explain Why is the surface of water in a graduated cylinder curved?
it is probably called figure it out, it is curved because glass is sticky. When you measure the volume from a graduated cylinder, measure at the bottom of it. It is called the meniscus.

Explain why the surface of water in a container is not flat but curved?
Surface tension.

What molecular attraction causes surface of the water to curve inside a glass?
The force of adhesion between water and glass molecules is greater than the force of cohesion between two water molecules.This causes the surface of the water to be curved. This curved surface is called a meniscus.
