when we add aluminium metal in ferrous sulphate what is its colour ?
when we add aluminium metal in copper sulphate what is its colour ?
what is the colour of zinc sulphate,iron sulphate,copper sulphate and aluminium sulphate respectively?
the aqueous solutions of copper sulphate and zinc sulphate appear?

c.blue and brown
d.blue and colourless
activity that to observe the action of Zn,Fe,Cu,and Al metals on the following salt solutions-ZnSO4 , FESO4 ,CUSO4 AND AL2(SO4)3
why is it important to clean the metals with sandpaper
How will the colour of the respective metal solutions cange when they react with metals ?
For eg : How will the colour of FeSo4 and CuSo4 change when it reacts with zinc and iron strip ? How will the colour of ZnSo4, CuSo4, Feso4 cahnge when it reacts with Aluminium metal ? How will the colour of Cuso4 change whne it reacts with iron metal ?
I hope the experts answer it as soon as possible as these questions about colour change come a lot in exams. And the colour change if each solution should be mentioned in the video itself.
The salt which gives a light green coloured solution when dissolved in water is:
a) CuSO4
b) FeSO4
c) ZnSO4
d) Al2(SO4)3
What happens when copper plate is rubbed with sand paper? what colour will be obtained?
what colour changes will be there when zinc reacts with ferrous sulphate and coppersulphate solutions? will there be any change in the metal strips?
when you place an iron nail in cuso4 the surface of the iron nail becomes

tomic number of al
are all stars move. if yes then how .
what are sacrificial electrodes.
The answer given by the meritnation expert for all india set 3 Q 36 tends to be wrong. I have referred many sites and book befor arriving at this conclusion. A change doesn't involve only the colour , there is a coating of zinc on the zinc piece. I hope the correction will be made.

a) pale green and light blue respectively
b) light blue and dark green respectively
c) dark blue and dark green
d) dark blue and pale green
a) at the head of the nail
c)at the middle of the nail.
b) at the tip of the nail
d) anywhere on the nail

A student added acetic acid to four test tubes A, B, C and D containing NaCl, NaOH, Na2CO3
what will be the infrence for this experiment?
i want to know the colour change of metal when added to each of the salt solutions
what will happen if we add a lot amont of zinc to small amount of diluted aluminium sulphate
What is the colour of solution when each metal is added to metal solution separately?
In which way the Cu,Fe,Zn are displaced in copper sulphate,ferrous sulphate and zinc sulphate because these metals are in the solution of there own metals ?
is there any practical based or viva question
the first capital of saudi arabia ?
what evidence do we have for the origin of life from inanmiate matter
Can someone give me a set of all mcqs for the preparation of class 10th secand term science '
Please
