What piece of lab equipment would you use to mix two liquids together?
To mix two liquids together in a laboratory setting, you would typically use a magnetic stirrer or a vortex mixer. A magnetic stirrer uses a rotating magnetic field to create a rotating stir bar inside the liquid, effectively mixing the two liquids together. A vortex mixer, on the other hand, uses a rapid back-and-forth motion to create a vortex in the liquid, mixing the two liquids together efficiently. Both pieces of equipment are commonly used in scientific research and experimentation for mixing liquids.
What equipment is used in titration at school?
In a school laboratory titration, you would typically use a burette to deliver the titrant, a pipette to measure the volume of the analyte, an Erlenmeyer flask to hold the analyte, a magnetic stirrer for mixing, and an indicator to show the endpoint of the titration.
Is the use of stirrer necessary during heating while determining the melting point of ice in laboratory?
Yes, using a stirrer is necessary during heating to ensure uniform temperature distribution. Without stirring, the temperature might vary within the sample, leading to inaccurate melting point determination. Stirring helps to achieve equilibrium and ensures an accurate measurement of the melting point of ice.
What science equipment are used during titration?
Some common science equipment used during titration include a burette for delivering precise volumes of titrant, an Erlenmeyer flask or beaker to hold the sample being titrated, a pipette for transferring small volumes of liquids, an indicator to show the endpoint of the reaction, and a magnetic stirrer to ensure thorough mixing.
What equipment used for stirring or mixing substances?
stirring rod
What is used to swirl or mix solutions?
A stir bar or magnetic stirrer is commonly used to swirl or mix solutions in a laboratory setting. The stir bar is placed in the solution and is rotated by a magnetic field produced by the magnetic stirrer, resulting in thorough mixing.
Why magnetic stirrer does not move?
Possible reasons why a magnetic stirrer does not move could be: the magnetic bar is not properly placed or is stuck to the sides of the container, the stirrer speed is set too low, the stir plate is not turned on, or the stir bar is not strong enough to be rotated by the magnetic field.
What is the function of stirrer?
The function of a stirrer is to agitate liquids for speeding up reactions or improving mixtures. The picture on the left is a magnetic stirrer used with hot plates. The picture on the right is a typical glass stirrer used in beakers or test tubes.
What is a stirrer in chemistry?
A stirrer in chemistry is a tool used to mix substances together by creating a swirling motion in a container. It is commonly used in laboratories to ensure homogeneity in solutions and to help facilitate reactions by promoting contact between reagents. Stirrers can be manual or automated and come in various forms, such as magnetic stirrers, overhead stirrers, and stir bars.
Why must the magnetic stirrer be stopped each time before reading the pH?
The magnetic stirrer must be stopped before reading the pH because the movement of the stir bar can cause fluctuations in the solution that could affect the accuracy of the pH measurement. Stopping the stirrer allows the solution to come to rest, giving a more stable reading of the pH.
What is a glass stirrer used for?
A glass stirrer is used to mix or stir liquids or solutions in laboratory experiments. It is typically made of borosilicate glass for chemical resistance and thermal durability. The smooth surface of the glass stirrer helps to ensure thorough mixing without introducing contaminants.

What is the working principle of Magnetic stirrer?
A magnetic stirrer is helpful for dissolving solids in liquids. As there are several different appearances, all of them will at least have a base with a speed-controlled spinning magnet inside and an exterior stirring bar. You place the stirring bar into a flask or beaker by tenderly sliding it beside the wall of the container. To avert fracture, don't drop the bar onto the bottom of the container. Place the container on the stirrer base and turn the speed control knob to its lowest set. Use enough speed to start the bar turning in the container. If using exact volumes, as with a volumetric flask, be sure take the measurements before adding the stirring bar.When stirring is finished, keep the stirring bar in the container by draft the liquid into another container. Carefully wash the original container and the stirring bar.
What tools do you use in a laboratory?
Examples are: oven, burette, muffle furnace, spectrophotometer, refractometer, analytical balance, stirrer and hundred others.
Can you used magnetic stirrer in lead acid battery?
Possibly, however I cannot see any function that it would serve.
What device should be used when powders must be combined with liquids?
A magnetic stirrer or vortex mixer can be used to combine powders with liquids efficiently. These devices help create a smooth and consistent mixture by applying stirring or vortexing action to the combination of the two substances.
What is operation process for hot plate with magnetic stirrer?
This particular hot plate is a common piece of laboratory equipment used for mixing solutions in the laboratory. It has a slow spinning magnetic field generated in the hot plate and this spins a plastic coated magnet placed inside the solution being heated. Turn the hot plate on, place the beaker with the solution on the hot plate. Place the magnet in the solution, adjust the temperature and speed of the magnet with dials on the front of the hot plate. This hot plate does not get hot enough usually for cooking.
