Why does magnesium displace copper from copper sulphate?
This is a simple displacement reaction - the more reactive magnesium displaces the less reactive copper from a solution of its salt. .... magnesium + copper sulphate ---> copper + magnesium sulphate Mg + CuSO4 ----> MgSO4 + Cu the blue colour of the copper sulphate will disappear and the silver coloured magnesium will be replaced by brown-red copper metal. Hope this helps. :)
Is copper positive or negative?
In speaker connectors, the copper-colored connector is usually positive, and the silver-colored connector is negative.
What are the names of the following compounds CaCl2 CuCl AgCl Mg3P2?
Calcium Chloride, Cuprous Chloride/Copper Monochloride, Silver Chloride, Magnesium Phosphide
Why is gold sliver copper used to make coins but not magnesium?
Magnesium is a highly reactive metal compared to gold, silver and copper. It will form a magnesium oxide as an outer-shell when it comes to contact with oxygen in the air, and it reacts with water, creating hydrogen gas and fizzing.
What are ten examples of metals?
Magnesium Tin Nickel Copper Gold Silver Zinc Iron Cobalt Aluminium
Why is magnesium most reactive if it reacts with hydrochloric acid among lead copper silver zinc iron?
Magnesium is more reactive than lead, copper, silver, zinc, and iron because it has a higher tendency to lose electrons and form magnesium ions. When magnesium reacts with hydrochloric acid, it displaces hydrogen from the acid to form magnesium chloride and hydrogen gas. This reaction is more vigorous compared to the reactions of the other metals mentioned.
What are the most important metal elements?
Answer: iron, aluminium, sodium, potassium, uranium, magnesium, copper, gold, calcium, silver etc.
Why is the magnesium the most reactive metal among silver copper lead zinc and iron?
Magnesium is the most reactive metal among silver, copper, lead, zinc, and iron because it has a high tendency to lose electrons, making it readily form compounds with other elements. Its outer electron configuration makes it easier for magnesium to react with other substances compared to the other listed metals.
Is silver more reactive then magnesium?
No. Magnesium is far more reactive than silver. Silver is one of the least reactive metals.
If copper displaces silver from silver nitrate will silver displace copper ll nitrate?
No, copper will not displace silver from silver nitrate and silver will not displace copper from copper nitrate. This is because the reactivity series dictates that silver is below copper, so copper can displace silver but not vice versa.
How did you work out the reactivity series of metals?
potassium sodium lithium calcium magnesium aluminium (carbon) zinc iron (hydrogen) copper silver gold
NAME OF A metal that replaces silver from silver nitrate solution?
copper will replace silver in silver nitratesolution will precipitate silver and oxidize copper turning to copper nitrate
