FAQs on Extraction of Metals Middle in the Activity Series part 1
| 1. What is meant by the extraction of metals in the middle of the activity series? |  |
Ans. The extraction of metals in the middle of the activity series refers to the process of obtaining metals that are moderately reactive. These metals are found in the middle of the reactivity series and require different extraction techniques compared to highly reactive or less reactive metals.
| 2. Which metals are categorized as being in the middle of the activity series? | |
Ans. Metals such as iron, zinc, lead, copper, and tin are typically considered to be in the middle of the activity series. These metals have moderate reactivity and are commonly extracted from their ores using methods like reduction or electrolysis.
| 3. What are the different extraction techniques used for metals in the middle of the activity series? | |
Ans. The extraction techniques for metals in the middle of the activity series depend on the specific metal. For example, iron is commonly extracted from its ore through the process of reduction using carbon or carbon monoxide. Zinc is extracted through a similar process called smelting, while copper is typically obtained through the process of electrolysis.
| 4. Why are different extraction techniques required for metals in the middle of the activity series? | |
Ans. Metals in the middle of the activity series have moderate reactivity, which means they are not as easily reduced or oxidized as highly reactive or less reactive metals. Therefore, different extraction techniques are necessary to separate these metals from their ores and obtain them in their pure form.
| 5. What is the significance of extracting metals in the middle of the activity series? | |
Ans. Extracting metals in the middle of the activity series is important because these metals have various industrial and commercial applications. For example, iron is used in the production of steel, zinc is used in galvanization, and copper is used in electrical wiring. By extracting these metals, we can harness their properties and utilize them in different sectors of the economy.

we saw metals of glory activity copper
and mercury being extracted just by
heating
what about metals of medium reactivity
question type zinc we shall learn only
about Z so in metals of medium
reactivity they are grouped into further
two types of ODEs they can be sulfides
or carbonates like I told you it can be
zinc sulfide it can be same traveling
will deal only with zinc but it extends
to in general metals of medium
reactivity so in medium reactivity these
sulfides and carbonates are not so weak
that just by heating you will get the
metal so you need to employ different
techniques and there are two techniques
which are employed for sulfides and
carbonates respectively two different
techniques one is called
calcination and the other is called
frosting now let us study about this
indifference form because very
frequently they ask the differences
between calcination and rose tree the
first thing okay when whenever you write
differences suppose difference between x
and y then first the point should be the
definition of x and the definition of y
and the definition should not be like
just the definition of x and just the
definition over just right the
definitions such that it looks like
there is a difference between x and y so
so just just don't write that X is a and
Y is B write something X is a while
y is not a something like that which
relates the two things the second
difference is related to some feature
and if there is a third difference you
can just give an example second
difference can be any feature as such so
calcination is basically heating
in limited supply of oxygen while
roasting is heating in excess of oxygen
so calcination they will be heating but
you will limit the supply of oxygen
i wildin roasting you will give excess
of oxygen so that it becomes combustion
as such not combustion but it's heating
in lib sufficient supply or excess
supply of oxygen secondly calcination is
used for carbonates
while roasting is used for sulfides so
we saw that metals of medium reactivity
can be grouped into carbonates and
sulfides and we see that carbonates for
carbonates this method is used for
sulfides this method is used we will see
why for carbonate calcination is used
and why for sulfides roasting is used
once we get to the reaction which is the
Third Point C there has to be an example
to fill out the Third Point and the
example in this case is the reaction so
you write the reaction I am NOT writing
it in the third point just writing it
separately in calculation you have zinc
carbonate
now if you heat it in limited supply of
oxygen you will get said an O plus co2
you still have not got Zeldin
please see about that you still have not
got the ring you have got ZN oh and in
case of roasting ZN s
we'll give you sale you know plus so2 so
you get zero from both the reactions but
in Z&S you have to form a so - so you
need extra oxygen to form this so2 in Zn
Co 3 you already have oxygen present in
ZN co 3 so it just breaks up into Z I
know it's you
you don't need oxygen as such extra
oxygen but in this case you need excess
oxygen so that s this sulfide can be
converted into an oxide and sulfur
dioxide
