Where do you read the meniscus?
Take the measurement at the bottom of the meniscus, not where it arches up against the sides.
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
Would a graduated cylinder be read at the middle of a meniscus?
The answer depends on the liquid, or more specifically, how the surface tension in the liquid affects the meniscus. It should be the top of the meniscus for liquids such as mercury but the bottom for liquids such as water or alcohol.
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.
Does a flask have a meniscus?
Yes. A meniscus is a visible curve in a liquid caused by the attraction of the liquid for the sides of the flask. Read the volume of your flask from the bottom of the meniscus.
What is the most accurate way to read a granguated cylinder?
At the bottom of the meniscus
When reading the volume of a liquid in the graduated cylinder or you must read from the bottom of the?
You must read from the bottom of the meniscus. In a narrow, graduated glass cylinder, water has a slightly domed surface, with the centre being higher than the side, so giving a false reading if the centre height is taken.
Which is the most most accurate way to read a graduated cylinder?
at the bottom of the meniscus
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.
What must be read very carfully when reading a liquid in a graduated cylinder?
the meniscus (the curved part of the liquid). For some liquids the meniscus is curved up so you read the bottom (assuming you can see through it to see the bottom), for some liquids it curves down so you read the top.
What tool must be read at the meniscus?
A graduated Cylinder needs to be read at the meniscus.
How is the meniscus used in measuring the volume of liquids?
AnswerA meniscus is when the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules. This causes the liquid to "stick" to the side of the container, creating a curve. The volume must be read at the bottom of the meniscus.
