What is a stirrer in chemistry?
The stirrer is a rod that you use to mix or stir the chemical solution.
How do you use stirrer?
Stirrers are used to stir solutions or pastes: to obtain a homogeneous mixture or to increase the reaction rate.
Why is a stirrer used when determining melting point of a solid?
The stirrer is used to homogenize the sample and his temperature.
How will you make standard solution?
mix a solute and solvent together and it will make a solution Increase the surface area of the solute with a mortar and pestle. Next measure out the mass of the solute. Add water and increase the temperature and use a magnetic stirrer. Do not fill to the necesary volume. Do not use a graduated cylinder instead use a volumetric flask. Pour solution into the flask. First measure the mass of the flask. rinse the beaker in which the solution was in. add more water to flask and fill to the needed volume. Then find the mass of solution.
In which direction would osmosis occur if 15 percent sugar solution is separated from a 25 percent sugar solution?
It would flow toward the weaker solution. The intent of osmosis is to gain equilibrium, so the 15 percent solution would gain sugar content until, if you allowed the osmosis to go to completion, the two solutions had the same amount of sugar in them. "Going to completion" doesn't necessarily mean 20 percent concentration on both sides. If you were to make a gallon bag out of dialysis membrane, fill it with 15 percent solution and put a stirrer in it, then drop it into a 25,000-gallon reaction vessel full of 25 percent solution with a stirrer in it, you might wind up with 24.9999999999 percent sugar solution in both bags.

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 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.
Can you used magnetic stirrer in lead acid battery?
Possibly, however I cannot see any function that it would serve.

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.
Can you make a back scratcher from a paint stirrer?
An effect back scratcher can be made from a paint stirrer in three ways. 1. Scratch your back with the stirrer without changing it in any way. 2. Attach a soft scratcher (such as a scrubby) to the stirrer. 3. Carve the end of the stirrer into a usable shape.

What equipment used for stirring or mixing substances?
stirring rod
Is david dobbs a stirrer?
No
What is the need and function of stirrer motor?
The role of stirrer is to stir with the goal to homogenize solutions, pastes, powders.
