What else can I help you with?
If you dissolve potassium bromide in water and add electricity What will happen?
If you dissolve potassium bromide in water and add electricity, the water will undergo electrolysis. Potassium ions will move towards the negative electrode (cathode), while bromide ions move to the positive electrode (anode). This process will lead to the decomposition of water into hydrogen gas and oxygen gas at the respective electrodes.
Which three products are formed by electrolysis of aqueous cesium bromide?
1) Caesium hydroxide2) Bromine NOT Bromide !!3) Hydrogen
What is the balanced equation for the electrolysis of aqueous potassium bromide?
2KBr + 2H2O----->2KOH + Br2 + H2(g) this is the reaction in electrolysis of KBr in aqueous solution
What acid and base are neutralized to give a sodium bromide salt?
Sodium Bromide is produced from the reaction of Hydrobromic acid and sodium hydroxide.
Product of alcoholic silver nitrate with ethyl bromide reaction?
When ethyl bromide, an alkyl halide, reacts with alcoholic silver nitrate (AgNO3), silver bromide (AgBr) and ethanol are produced. This reaction is a substitution reaction where the bromine in ethyl bromide is replaced by the nitrate ion from silver nitrate.
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.
If you dissolve potassium bromide in water and add electricity What will happen?
If you dissolve potassium bromide in water and add electricity, the water will undergo electrolysis. Potassium ions will move towards the negative electrode (cathode), while bromide ions move to the positive electrode (anode). This process will lead to the decomposition of water into hydrogen gas and oxygen gas at the respective electrodes.
What is the observation at the anode during electrolysis of concentrated potassium bromide?
At the anode during the electrolysis of concentrated potassium bromide, bromine gas is produced. This occurs because the bromide ions are oxidized to bromine atoms, which then combine to form bromine molecules.
Why does lead bromide have to be molten for electrolysis to occure?
Lead bromide must be molten for electrolysis to occur because in the molten state, the ions are free to move and conduct electricity. This allows for the dissociation of lead bromide into its ions, which can then be attracted to the electrodes for the electrolysis process. In the solid state, the ions are not mobile and cannot participate in the electrolysis reaction.
Which three products are formed by electrolysis of aqueous cesium bromide?
1) Caesium hydroxide2) Bromine NOT Bromide !!3) Hydrogen
How could lead bromide be made into a liquid for electrolysis?
Lead bromide can be dissolved in a suitable solvent, such as water or an organic solvent, to form a liquid electrolyte solution for electrolysis. Heating the solvent can help in dissolving the lead bromide more efficiently. Ensure that the concentration of lead bromide in the solution is appropriate for the electrolysis process.
Name the metals extracted by electrolysis?
aluminium bromide lead
How do you collect the silver from silver bromide?
by electrolysis or by chemical process
Which elements would you get when electricity is passed through molten lead bromide?
When electricity is passed through molten lead bromide, the lead bromide will undergo electrolysis. This process will result in the decomposition of the lead bromide into its constituent elements, which are lead and bromine. Lead will be deposited at the cathode, while bromine gas will be produced at the anode.
Where can you get the element bromine?
You can obtain bromine from natural brine wells and underground deposits, as well as as a byproduct of seawater desalination. It can also be produced through industrial processes such as halide exchange reactions or electrolysis of bromide salts.
Why does electrolysis not occur unless lead II bromide is molten?
Electrolysis requires the movement of ions to conduct electricity. In solid lead II bromide, the ions are held in fixed positions and cannot move freely to carry an electric current. When lead II bromide is molten, the ions are free to move and can participate in electrolysis.
What is the positive ion name in sodium bromide?
The positive ion in sodium bromide is sodium, which has a charge of +1.
