Why do we add liquid above the calibration mark when using a pipette? Why do liquids in a graduated cylinder form a meniscus? Why is it suggested you use weighing paper or a watch glass instead of filter paper on which to allow a sample to dry? Explain. ...
and I had a great chemistry set as a kid. I was also looking for a set to bring back a few memories, but the modern versions are so safe and boring it is unbelievable that people buy them. We used to get all sorts of interesting chemicals in the old kits (and no safety glasses)...
A volumetric pipette is a carefully graduated glass tube that is designed to suck up, measure, or transfer a quantity of liquid...

In science (physics, and chemistry), the volume is a kind of representation or indication that is used to represent or indicate the total amount of three-dimensional space enclosed by an object or a body. Various types of units (like meter cube, centimetre cube, cubic inch, etc) are used...
Dilution is the method in which the solute concentration generally lesser by mixing with more solvent like adding more solvent to a solution. In this process, the solvent helps to solution become more diluted and lesser the quantity of solute in that....
The Role of Titrants in Chemistry By Anne Marie Helmenstine, Ph.D. How a Titration Is Performed A typical titration is set up with an Erlenmeyer flask or beaker containing a precisely known volume ofanalyte(unknown concentration) and a color-change indicator. A pipette or burette containing a...
