When a liquid is held in a vessel, the water adheres to the side of the vessel. So when the amount of liquid held by the vessel is less than the full amount the vessel will hold, the liquid level rises where it touches the vessel. It "sticks" to the side of the vessel hard enough to be above the top of the liquid. This is called a negative meniscus. When the level of the liquid is higher than the top of the vessel (but doesn't overflow the top due to the surface tension of the liquid), then there is a positive meniscus.

∙ 12y agoWhen a LIQUID is kept in a beaker or any apparatus in cylindrical shape the lower level of the liquid is called as meniscus level of the liquid.
Eg:- when we test normality of a base or a acid in a burette or in a pipette meniscus level of the liquid decides the normality of the respective acid or base.

When measuring you do the measurement from the bottom of the meniscus?
You should always measure at the lowest part of the meniscus. The meniscus is a slight curvature at the top of a liquid in a container.
How is a meniscus used in measuring?
As the diameter of the container decreases, the meniscus becomes more pronounced. The meniscus may be convex (curving upward) or concave (curving downward). Most of the time you will find that the meniscus is concave. The most notable exception is the meniscus that forms from mercury. When taking measurement readings it is important that the reading is done properly. The following rules must be adhered to: I. Read the meniscus at eye level. Do not read the meniscus from above or below eye level. Significant measurement errors may occur II. Read the bottom of a concave meniscus and the top of a convex meniscus.
Why should liquid volumes be read at eye level?
Liquid volume readings should be at the bottom of the menicus or at the level of the liquid in the middle of the container. The accuracy of the reading may vary slightly with the viscosity of the liquid and the diameter of the container.
What meniscus is being read if you measuring the volume of dark colored liquids?
1.read the bottom of the curve 2. you must read the meniscus at eye level
What is a meniscus in chemistry?
meniscus is when you fill the beaker upwith liquid. when yo go down to look at the beaker with eye level, you see a dip. that's the meniscus. -used in science
What is the scientific definition of meniscus?
meniscus is the level of a liquid in a cylinder.
What is the lowest point of the water level in a graduated cylinder called?
It's called Ya Mum's Panis
What is the zero correction and meniscus correction in hydrometer analysis?
· Zero Correction (Fz): If the zero reading in the hydrometer (in the control cylinder) is below the water meniscus, it is (+), if above it is (-), if at the meniscus it is zero.· Meniscus Correction (Fm): Difference between upper level of meniscus and water level of control cylinder.

What is the meniscus line?
A meniscus line is the little line that you have at the top of a liquid. If you fill a glass up with water, the line that seems to sit at the top of the water that you see when you look at the glass at eye level is the meniscus line.

When using a graduated cylinder you measure the level of the water from the bottom point of the curve what is it called?
a meniscus
When reading the volume of fluid in a graduated cylinder the eye should be .?
Level with the bottom of the fluid's meniscus
