Metal Oxides (Part - 4) - Metals & Non-Metals, Science, Class 10 Video Lecture

hello friends this video on metal and
nonmetal part 4 is brought to you by
exam Viacom no much fear from exam
before watching this video please make
sure that you have watched part 1 - Part
3 chemical property of metals we have
learnt physical properties of metals
physical property of iron metal
now let's learn chemical property of
metals metal burns metal burns that is
almost all the metals when you burn it
combines with oxygen to form metal
oxides and they are basic example you
have manganese you take any metal you
take oxygen oxygen is something which is
available in the air so when you heat it
then you burn it actually it form metal
oxide some metals form metal oxide even
without burning
they are so reactive it's amber sodium
right so generally metal plus burn when
you burn metal that is knew he didn't
reserve oxygen
it gives metal oxide and they actually
basic nature right example this you take
manganese you burn it you burn this guy
right
you get Magnus and as I told this oxides
the metal oxides are basic to prove that
but you can do that you have this metal
oxide you take acid you are reacted you
will get solved and we know that base
plus as it kills someone right that
means it is base correct see I just told
you that they are basic but how to
confirm that right you begin now sir you
have told it's basic but how to confirm
that so to confirm that you can take
this metal oxide to react to they say
and you get salt in water and we know
that base plus AC visible do small plus
water this thing we know from the last
chapter we have learned this right basic
base reaction so that guy
that means metal oxide is basic so you
take this copper oxide you add with you
do experiments the same thing the
hydrochloric acid you get shoes here
there is a salt plus what correct so you
for experiments you can go to lab you
can ask for a copper oxide you have
hydrochloric acid to indicate salt and
what
the next question is are metal oxides
water-soluble the answer is most of the
oxides are insoluble except calcium
medium and the group one elements
correct because they don't react to God
you don't dissolve actual but they react
with water so all this Krupa and sodium
potassium right
those guys they don't dissolve water but
they react with water so actually they
are you can say they are insoluble but
the group one elements and the Casman
rhenium they are so reactive with what
is the react and then you feel it absorb
actually right so they don't dissolve
but they actually reacted what but other
or other metal oxide example copper
oxide aluminum oxide right they don't
dissolve in water they don't dissolve
they don't resolve thank you
