According to the reactivity series, iron is more reactive than ________.
potassium
sodium
copper
calcium
copper
According to the metal reactivity series, iron (Fe) is situated above copper (Cu), meaning iron is more reactive than copper and can displace it from its salt solutions.
According to the metal reactivity series, iron (Fe) is situated above copper (Cu), meaning iron is more reactive than copper and can displace it from its salt solutions.
Think of it like an arm-wrestling contest where stronger metals (higher in the series) easily push weaker metals out of their current combinations, just as iron easily displaces copper from copper sulfate solution.
Please Stop Calling Me A Careful Zebra, Instead Try Learning How Copper Saves Gold (Potassium, Sodium, Calcium, Magnesium, Aluminium, Carbon, Zinc, Iron, Tin, Lead, Hydrogen, Copper, Silver, Gold).
Fe+CuSO4тАЛтЖТFeSO4тАЛ+Cu тАФ Displacement reaction of copper by iron
In the chemical reactivity series (activity series), metals are arranged in order of decreasing reactivity. A metal higher up in the series has a higher tendency to lose electrons and undergo oxidation, thus displacing any metal below it from its aqueous salt solution (e.g., Fe+CuSO4тАЛтЖТFeSO4тАЛ+Cu). Since iron lies above copper, it is more reactive than copper.
The reactivity series is a list of metals arranged in order of their decreasing chemical reactivity.
Metals placed above hydrogen can displace hydrogen from dilute acids.
A more reactive metal displaces a less reactive metal from its salt solution.
Iron (Fe) is placed above copper (Cu) in the reactivity series.
Helps predict the outcome of metal displacement reactions
Useful in metallurgy for extracting metals
Understanding corrosion and rusting prevention
Predicting feasibility of single displacement reactions in chemical analysis
Potassium, sodium, and calcium are extremely reactive metals placed at the top of the reactivity series.
Copper, silver, and gold are less reactive metals placed below hydrogen.
C is correct тАФ According to the metal reactivity series, iron is more reactive than copper.
Always remember that metals higher up in the reactivity series act as stronger reducing agents because they lose electrons more easily.
