A voltammeter is a type of scientific instrument used for measuring electrical quantities. These are measured in two SI units: the electric potential (volt) and the electricity's quantity (coulomb).

What are the apparatus used to determine volumetric composition of water?
The apparatus used in laboratory to determine the volumetric composition of water is called Hofmann Voltameter. A Hofmann voltameter is an apparatus for electrolysing water, invented by August Wilhelm von Hofmann in 1866. It consists of three joined upright cylinders, usually glass.
Where can you buy a Hoffman voltameter?
I've been looking myself! You can easily make a simple apparatus to test the concept. However, here is the professional blown glass apparatus: http://www.sci-supply.com/closeup.asp?cid=131&pid=145&offset=0 Hope this is helpful!

Could a lemon battery power a motor?
Yes because the acidity level determines the PH level which when steel and copper are hooked into the lemon and hooked onto a battery it will start to charge.
How do you install a radio in a 1985 Holden Astra?
firstly take out the old stereo.. using a voltameter find the 12v supply cable.. this should always be on even when ignition is off then find the accessories power cable with the ignition turned to on. hook up the earth cable on any metal surface in the car use a 6 volt battery to find the speaker cables go thru the wires until you hear a "pop" sound and this will indicate which speaker is from which wires. hook up all wires (for a better installation solder the wires and cover with tape but if you cant sodler just twist together and tape) and replace stereo in the dash.
How do fix rear electric window in 84 ford full size bronco if there is power going through the wires but still not going down?
I just did this in my 85 bronco. I don't Know what if anything you tracked is right so I'll start from the begining. With 2 people and a voltameter. Open your tail gate. Go in the back and open the panel on your tailgate there is a wire connector on the inside of the tailgate, disconnect and put a voltameter on it, have the other person turn the switch up and down. If you see your 12 volts come on you are good to that point. If not its your wire's or switch.If it's your wire it is pobably between your tailgate and the truck on the drivers side. If you your good to this point than with a 5/16 socket remove the three bolts that hold's your motor in place and pull your motor out and reconnect it to the wireing, and turn your switch on and off. Does it move the gear? Is your ingtion turned to the on postion. If your gear does not turn go get another one form the dealer or junkyard. Also - There is a safety switch in the left tailgate latch that will disable the window motor if it is not shut. If you push the latch in you can work on it with the tailgate down. When you take out the motor remove the gear cover and look at the spacers they will probably be shattered. I have heard of using nuts as a replacement. Open up the motor and with a volt meter test the wires from the brush to the plug. If you left the switch on up front you may have caused internal circuit breaker to be permanently open. If you see that just bend them back together. Put the motor back together carefully and give it a try.
Which compounds are used in laboratory prepration of oxygen gas?
Lab preparation of oxygenTo prepare oxygen; you would need the following apparatus:1.Test tubes2.Manganese (IV) dioxide (MnO2)3. Hydrogen peroxide (it must be fresh and kept away from light)(H2O2)4. Wooden splinter (only needed if you are going to check how oxygen helps in combustion).5.Candle and matchsticks.Method:1.First, take the test tube and put a little bit of MnO2 (Manganese dioxide)2. At this time, you will need a friend's or someone else's help (only if you are requiring it to check how oxygen helps in combustion). First, tell your friend to light the candle and to ignite the splinter using the candle. At that time, take a small amount of hydrogen peroxide in a beaker or test tube. Then, tell him/her to to bring the wooden splinter close to the test tube. As soon as he/she brings it, put a little bit of hydrogen peroxide (not more than 1ml). You should see the reaction forming a gas, which looks like smoke. This gas is Oxygen.3. What happens to the splinter when you bring it close to Oxygen? Of course!The splinter burns more brightly and intensely.4. Should you want to only collect Oxygen, you need not do the second part of the second step.Precautions:1. Do not drop the test tubes.2. Always wear gloves while performing chemical experiments.3. Always wear lab coats while doing the same.4. Do NOT eat or manganese oxide or rub them on your eyes. Serious problems may occur, which even might result in blindness or death.5. Do NOT put warmed hydrogen peroxide on your skin. You might get a boil.6. Never stand too close to the test tube.7. If you are untrained, always seek for someone who is better at you in performing lab experiments, or anyone who already has done the lab preparation of Oxygen.8. Keep H2O2 and MnO2 away from children.9. If Oxygen gets into your eyes and you get an irritation, wash your eyes with cold water immediately.I am sure this helped! Good luck in becoming a RAD scientist!
