What else can I help you with?
What is produced at the positive electrode of the electrolysis of molten lead bromide?
At the positive electrode (anode) of the electrolysis of molten lead bromide, bromine gas is produced. This is because bromine ions are attracted to the positive electrode, where they are oxidized to form bromine gas.
What is lead selector?
Eeach electrode connected to the patient
Where is the negative electrode placed in lead 2?
right arm
What metal is used to make the electrodes in automobile batteries?
Lead is commonly used to make the electrodes in automobile batteries. Lead-acid batteries are the most common type of battery found in cars, and they consist of lead dioxide as the positive electrode and sponge lead as the negative electrode.
Can pencil lead be used as an electrode?
Pencil "lead" is actually a mixture of graphite and clay, and is not an ideal choice for an electrode due to its impurities and inconsistent conductivity. It is better to use pure graphite or metal electrodes for more accurate and reliable results in electrochemical experiments.
What happens if the metal tip of a lead wire becomes detached from an electrode?
If the metal tip of a lead wire becomes detached from an electrode, it can result in a poor or lost connection, leading to faulty readings or loss of signal. This can impact the accuracy and reliability of the data being collected from the electrode. It is important to promptly replace or repair the lead wire to maintain proper functionality.
How do you make lead from lead 2 bromide?
Lead can be obtained from lead (II) bromide through a process called electrolysis. When lead (II) bromide is melted and electrolyzed, the lead ions migrate to the negative electrode (cathode) and are reduced to form lead metal, while bromide ions move to the positive electrode (anode) and are oxidized to produce bromine gas. This allows for the isolation of lead from lead (II) bromide.
Which electrode will be negative if you connect magnesium and lead in one cell?
the magnesium would be negative
What substance is reduced in a lead-acid storage battery?
Lead dioxide on the positive electrode is reduced to lead sulfate during discharge in a lead-acid storage battery.
If electrode use in welding has moisture what effect will it have on the weld?
Electrodes with too much moisture may lead to cracking or porosity.
For what red lead is used in battery?
Red lead (lead tetroxide) is used in batteries as a component of the paste that coats the positive electrode plates. It helps improve the overall performance and efficiency of lead-acid batteries by enhancing the electrode's conductivity and increasing its resistance to corrosion.
What is a lead alkaline battery?
The positive electrode is made of lead oxide, the negative of any of the following metals: iron, lead, zinc or cadmium. The electrolyte can the hydroxides of any of the alkali metals (such as sodium). Please see the link.
