Acid & Base react with Metals - Acids, Bases & Salts Video Lecture - Class 10 | Best Video for Class 10

children do you know acids and bases
react with metals yes it is acids and
bases react with metals
how do acids and bases react with metals
let us see the experimental activity a
reaction of zinc granules with dilute
sulfuric acid and testing hydrogen gas
by burning requirements test tube stand
dilute h2 so4 zinc granules delivery
tube tub soap solution and candle
activity take test tube containing 2 to
3 milliliters of dilute sulfuric acid
and also add fusing granules to it cover
the test tube with rubber cork
observe the surface of the zinc granules
what do you observe we can observe the
hydrogen gas with the appearance of
bubbles
pass the gas being evolved to the sub
solution bubbles form keep the burning
candle near a gas filled bubble what do
you observe we can observe the burning
of hydrogen gas with a pop sound which
is a confirmatory test for hydrogen gas
that means metal displaces hydrogen from
the acids
h2 so4 plus Zn gives ZN s fo plus h2
acid plus metal give salt plus hydrogen
gas also note that metal combined with
the remain part of the acid to form a
salt similarly we can observe the
reaction of zinc granules with sodium
hydroxide solution which also from
hydrogen gas to NaOH plus Zn give na to
Zn o to sodium zincate plus h2
