What are the different applications of electrolysis?
1. electroplating 2. extraction of metals from ores 3. electrolytic refining 4.electrolysis can also be used for coating artificial jewelery with gold to give it an attractive look . 5.electrolysis can also be used for coating cutlery made up of cheap metal with silver to give it an attractive look .
Aluminium oxide can be separated by electricity?
there are two ways of extracting aluminum from its ore 1) old way: - displacement reaction ex: - Na + Al2O3 ==> Na2O + Al 2) new way: electrolysis electrolysis: - is a way of extracting highly reactive metals from their ore using electricity. so the short answer is YES
Which group in the periodic table contain only metal?
There are many groups in the periodic table that only contain metals. There are the Alkali metals, the Alkaline earth metals, Lanthanoids, Actinoids, Transition metals, and the Post-transition metals.
What are refer as group 2 metals?
they would be refered to alkaline earth metals, im only in 5th and i know.
What is the ratio of gases evolve on electrolysis of water?
at the ration of 2:1

What are the ionic charges in the transition metals?
Metals form ions with charges of +1, +2, or +3. Those are the only options for metals.
Why do group 1 and group 2 metals conduct electricity?
ALL metals do conduct electricity, not only those of group 1 and 2.

What apparatus is used in the electrolysis of water?
1voltmeter 2
In what compuonds is oxygen found and how is it extracted?
Oxygen can be found in H20 (water). It can be separated through electrolysis The equation for the electrolysis of water is 2[H20]+energy = 2[H2] + 02
What is the electrolysis of sodium chloride?
1. The products of the molten sodium chloride electrolysis are sodium and chlorine. 2. The products of the water solution of sodium chloride electrolysis are sodium hydroxide and hydrogen.
Why are the alkaline earth metals less reactive hen the alkali metals?
The alkaline earth metals are in group 2 of the periodic table this means they have 2 electrons in each of their outermost energy 'shells'. The alkaline metals are in group 1 and only have 1 electron to lose in a reaction rather than 2. This means the alkaline metals react more readily.
Which metals are not metals?
4 metals are not magnetic 1. Aluminium 2. Gold 3. Copper 4. Brass these metals can only be magnetised by very scientific work which i cannot understand 5. don't forget silver...
What is the ratio of gases evolve on electrolysis of water?
at the ration of 2:1
