Law of lower and upper meniscus levels in determining liquid solution?
Wiki User
∙ 14y ago
In measuring liquids using graduated cylinder, there are two things to consider. 1.) CLEAR LIQUID and 2.) COLORED LIQUID (as we may say) In identifying the volume of CLEAR LIQUID (e.g. plain water, oil, alcohol, etc.), THE LOWER MENISCUS is read. For the COLORED LIQUID (e.g. soy sauce, ketchup, etc. ) the upper meniscus is get, since there is only one meniscus there.. (meaning there is no upper & lower meniscus.)

The law of lower meniscus states that the level of liquid in a capillary tube will be lower due to adhesive forces between the liquid and the walls of the tube. The law of upper meniscus states that the level of liquid in a capillary tube will be higher due to cohesive forces within the liquid itself. These principles are important in determining the surface tension and properties of liquid solutions.

Which meniscus is to be seen in the burette containing kmno4 solution and why?
In the burette containing KMnO4 solution, the concave meniscus is observed. This is because KMnO4 is a colored solution that has strong adhesive forces with the glass walls of the burette. As a result, the liquid molecules are more attracted to the glass, causing the meniscus to curve downward.
Does a flask have a meniscus?
Yes, a flask can have a meniscus. The meniscus refers to the curvature of the liquid surface in response to the container's shape. A flask with a narrow neck can exhibit a concave or convex meniscus, depending on the liquid it contains.
What is the name of the curve at the top of a liquid in a container?
meniscus
What is called when measuring a liquid in a container and you have a parabola at the top of liquid in the container?
The curved surface at the top of a liquid in a container is called the meniscus. When measuring a liquid in a container, it's important to read the measurement at the bottom of the meniscus to ensure an accurate reading.
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.
What is the curved surface of a liquid called?
Meniscus
What is a curved surface on a liquid called?
A meniscus, but whether it has a positive curve or a negative one depends on whether it wets the glass.
Does a flask have a meniscus?
Yes, a flask can have a meniscus. The meniscus refers to the curvature of the liquid surface in response to the container's shape. A flask with a narrow neck can exhibit a concave or convex meniscus, depending on the liquid it contains.
What is the scientific definition of meniscus?
meniscus is the level of a liquid in a cylinder.
What liquid's meniscus curve up?
Water's meniscus curves up. Mercury's meniscus curves down.
When water is in a container the surface of the water is curved this curve is called?
The meniscus - the upward curve of a liquid in a narrow vessel.Read more: When_water_is_ina_container_the_surface_of_the_water_is_curved_this_curve_is_called
Does meniscus always concave?
No, the meniscus is not always concave. It can be convex or flat depending on the liquid and the surface tension between the liquid and the container.
What is the curve at a liquid?
The curve at the top of a liquid is the meniscus
What is a meniscus in chemistry?
In chemistry, the meniscus refers to the curve seen at the surface of a liquid inside a container. It is caused by the surface tension of the liquid, and is used to accurately measure the volume of a liquid in a graduated cylinder or similar vessel.
What is the curve at a liquid surface?
The meniscus, which is creaded by adhesion of the liquid particles to the surface of the container. Water meniscus domes upwards - the water has greater bonding to its own molecules; Mercury meniscus domes downwards.

meniscus
What is the curved surface of the liquid?
