What metals are low in the activity series?

What metals are low in the activity series?

Metals that are low in the activity series are very un-reactive. The oxides of these metals can be reduced to metals by heating alone. For example, mercury is obtained from its ore, cinnabar (HgS), by the process of heating.

What metals are high in activity series?

Those metals that can displace H+ ions from acids are easily recognized by their position above H in the activity series….P3: Activity Series of Metals.

Where are the least reactive metals of the activity series?

bottom
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom.

What is activity series of metals which are the most and least reactive metals?

In general, the alkali metals are the most reactive, followed by the alkaline earths and transition metals. The noble metals (silver, platinum, gold) are not very reactive. The alkali metals, barium, radium, strontium, and calcium are sufficiently reactive that they react with cold water.

How metals low in the activity series and in the middle of the activity series are extracted explain in detail with chemical equations?

Answer: metals low in the reactivity series are very unreactive and oxides of these metals can be reduced by heating alone. when enough amount of copper oxide is formed the supply of oxygen is cut off and then the remaining copper oxide react with copper sulphide to form copper metal.

How are the less reactive metals which are quite low in the reactivity series extracted explain with the help of an example?

The metal which has low reactivity can be extracted by heating the ore alone. Metals are extracted from these ores by heating them alone. For example, ores of copper can be extracted by reduction with carbon (copper (I) oxide) as well as heating alone (copper (I) sulphide).

Why is metal activity series?

The relative reactivity of metals can be used to organize them into an activity series. Once organized, an activity series helps us to predict if a reaction will occur when a piece of elemental metal is placed in water, an acid solution, or a solution containing the ion of another metal.

How are metals lying in the middle of activity series extracted?

Extraction of metals which are in the middle of activity series. A metal is obtained from its ore by the processes of reduction or by electrolysis. In the reduction process, it is the oxide ore that is reduced. It is easier to reduce an oxide ore as compared to its sulphides and carbonates.

How is metals of less reactivity extracted?

Metals more reactive than carbon, such as aluminium, are extracted by electrolysis, while metals less reactive than carbon, such as iron, may be extracted by reduction with carbon. However, chemical reactions may be needed to remove other elements that might contaminate the metal.

What is the activity series of metals?

The activity series is a list of elements in decreasing order of their reactivity. Since metals replace other metals, while nonmetals replace other nonmetals, they each have a separate activity series. The table 7.11. 1 below is an activity series of most common metals, and the table 7.11. 2 is an activity series of the halogens.

What happens to the reducing ability of metals as they travel down series?

The reducing ability of the metals grows weaker while traversing down the series. The electro positivity of the elements also reduces while moving down the reactivity series of metals. All metals that are found above hydrogen in the activity series liberate H 2 gas upon reacting with dilute HCl or dilute H 2 SO 4.

How do you replace a metal in an activity series?

In an activity series of metals, a metal can only replace a metal that is below it in the series. In a single replacement reaction, a metal and a metal compound may react so that the metal will replace the metal in the compound, producing the replaced metal and a new compound with the original metal.

What is the activity series used for in chemistry?

It can be used to predict the products in similar reactions involving a different metal. The activity series is a chart of metals listed in order of declining relative reactivity. The top metals are more reactive than the metals on the bottom.
