Glass rods are used for stirring, because the glass is inert to most chemicals.They are used as guides to pour a liquid down when transferring containers. This stops the liquid from getting all over the sides of the new vessel.
The end can be used to break up solid lumps when dissolving.

What is a science lab procedure?
Scientists are proud and sure of their work for this reason: their independently performed experiments can be reproduced, with the same results obtained, anywhere in the Universe. Pick a science. A chemistry lab procedure will plate the inside of a test-tube with silver, making a mirror ; or winding strands of newly synthesized nylon around a (glass) stirring rod.
What happens to the rod when it is rub by nylon?
Oh, dude, when you rub a rod with nylon, it transfers some of its electrons to the rod, giving it a negative charge. This is because nylon has a higher affinity for electrons than the rod. So yeah, the rod gets all charged up and ready to party with some static electricity.
What is the function of hard glass test tube?
It's actually very simple. Glass tubing is a long, clear tube used as a passage for liquid or gas in experiments. Rubber stoppers are used as plugs in flasks or test tubes. Rubber tubing is often connected to a condenser, which is a laboratory tool used in the process of distillation. The rubber tubing helps cool water to flow in and out of the condenser and helps the heated water vapour in the condenser return to its liquid state.
When a glass rod is immersed in the colourless liquid the glass rod seems to be deappeared why?
Hey! The reason it seems to disappear is because of the refraction and absorption of light and colour. When light enters the colourless liquid, colour is obviously absorbed. The light waves refract ("bounce") off the glass test tube and leave the glass beaker (containing the colourless liquid). Because the liquid and solid are the same colour, it creates the illusion of the test tube disappearing.
What was everything Benjamin Franklin invented?
He invented the lightning rod, bifocals, the Franklin stove, a carriage odometer, and the glass 'armonica'.
What is used to mix liquid in a lab?
Normally a small glass rod.
What is the purpose of glass rod in laboratory?
It is used for grinding and mixing chemicals in lab.
What is the function of glass stirring rod?
to mix chemicals during a lab.
What is a glass stir and what is it used for?
It's a short piece of cylindrical glass, usually about 12 cm long. It's used for stirring chemicals together. It's useful because glass is inert to most chemicals and won't contaminate anything.
What is glass stirring rod used for?
The function is in the name: a glass stirring rod is used to stir solutions or mixtures. Mixing will speed up any reaction that takes place in the test tube or flask. A glass stirring rod can also be used for decanting (pouring off) a liquid from a precipitate or sediment.
What are glass rods used for in chemistry?
Glass rods are commonly used in laboratories for mixing, stirring, and transferring liquids during chemical experiments. They are inert and resistant to chemical reactions, making them suitable for a variety of applications in the chemistry lab. Glass rods are also used to spread chemical compounds evenly across a surface, such as when performing thin-layer chromatography.
When a glass rod is rubbed with a silk cloth the charge produced in the glass rod is?
When a glass rod is rubbed with a silk cloth, the glass rod becomes positively charged. This is because electrons are transferred from the glass to the silk, leaving the glass with an excess of positive charge.
How a glass rod charged when rubbed with wool?
When a glass rod is rubbed with wool, electrons are transferred from the wool to the glass rod, making the rod negatively charged. This transfer of electrons causes the glass rod to become statically charged, meaning it has an excess of negative charge.
WHY MOST OF APPARATUS made up of metal?
Lab tools must be made of different materials so that they can be used under different circumstances. A glass stirring rod is nonreactive, but is useless when dealing with extremely high temperatures. Likewise, a metal stirring rod may be useful, but not if it reacts with the solution.
If a glass rod were rubbed with silk and a plastic rod with wool how would the glass rod react with wool?
the rod slightly attract each other
What is stirring rod?
A stirring rod is a tool used in the laboratory to mix or stir substances in a beaker or test tube. It is typically made of glass or metal and is long and slender, allowing for easy manipulation and thorough mixing of liquids or solutions.
What happen when a glass rod is rubbed with fur?
Rubbing a glass rod with fur transfers electrons from the fur to the glass rod, giving the glass rod a negative charge. This charge separation creates an attractive force between the glass rod (negative charge) and the fur (positive charge), causing them to be attracted to each other.
