What is the use of the glass rod in transferring liquid reagents?
Wiki User
∙ 13y ago
The glass stirring rod is used in liquid transfer in order to prevent spillage and facilitate the maximum amount of liquid transferred from one vessel to the next. The liquid's surface tension, or the fact that like molecules will tend to "stick" to each other make the liquid transfer virtually seamless from the lip of one vessel, to the stirring rod, and into the receiving vessel.

Why should use a glass rod when pouring a liquid into a narrow-mounted container?
A glass rod should be used when pour liquid into a narrow mouthed container because of the adhesive force between the glass and the liquid. This will cause the liquid to run down the glass rod and into the narrow mouth without spills.
Why do you need a glass rod in transferring liquids especially corrosive ones from one container to another?
To avoid splashing and losses of solution.
When rubbing a wool sock on a glass rod what transfers to the sock?
The described action will leave the wool sock positively charged, as electrons will be transferred to the glass rod.
Will a positively charged glass rod be attracted to a magnet?
no.
Why the charged balloon wiill be attracted to the charged glass rod?
If charge on the balloon is induced due to the charge of the glass rod then there will be opposite charge and so balloon gets attracted by the rod. Unlike charges do attract each other

What is a straight glass rod used for in the lab?
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 used to mix liquid in a lab?
Normally a small glass rod.

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 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.
How can a liquid be transferred from a beaker to a funnel without running down the outside walls of the beaker?
There is a technique of pouring down a glass rod detailed here: a glass rod is held across the top of the beaker with one end sitting in the beaker's spout and extending approx. 2 to 3 inches beyond the wall of the beaker. The beaker is then tilted, slowly, with the rod pointing into the top of the funnel, until the liquid contents run along the rod and drip into the funnel.
What happens when you place a hot glass rod in a cup filled with cold liquid?
it depends on how hot the glass rod is if its hot enough the glass rod will heat up the liquid and the liquid will keep on getting hotter and in the end it will reach over heat and just explode if its not hot enough then the liquid will just rise other then that i have nothin HOW I KNOW THIS we'll i don't know heaps about sisence but i do know one thing when cold liquid is heated to much it expodes so here's a tip for you if you do have a cup of liquid in winter its fine if you leave it out but in summer put it in your freezer because it'll most likely over heat and explode
You place a hot glass rod in a cup filled with a cold liquid describe what will happen to the rod and the liquid with time?
They'll eventually reach the same temperature.
Why the end of a glass rod becomes round on heating reason?
when glass rod is heated ,it melts. Now a liquid having surface tension ,tends to have least surface area.we know that a spherical surface has least surface area compared to other shapes of same volume.so end of a glass rod becomes round when heated .........geddit :)
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
