How do you measure a meniscus?

For a concave meniscus, the volume of the liquid in the container is read from the bottom of the curve. You may notice a ‘line’ of liquid at the very top, forming the curve itself. The bottom of the curve is the lower side of this line.Click to see full answer. Correspondingly, when using aqueous solutions do we read the bottom or top of the meniscus?Concave menisci are read from the bottom of the curve at eye level. A meniscus is a curve formed on the upper surface of a liquid inside a container. This curve is formed by the surface tension between the liquid and the container holding the liquid.One may also ask, what is upper meniscus and lower meniscus? A concave meniscus curves downward; if you are looking down from the top, it curves away from you, like the opening of a cave would. In contrast, a convex meniscus curves upward; if you are looking down into the container, the meniscus curves toward you. Considering this, why do we read the bottom of the meniscus? The Meniscus. Normally, liquid will curve at the edges of the surface where the liquid touches the container because water molecules are more attracted to glass than to each other. We need to read the level at the bottom of the meniscus to measure a volume of liquid in a graduated cylinder.How is a meniscus formed? Why a meniscus occurs Water molecules are attracted to the molecules in the wall of the glass beaker. And since water molecules like to stick together, when the molecules touching the glass cling to it, other water molecules cling to the molecules touching the glass, forming the meniscus.
