Where's Daadi?

Sodium can be used for Sacr. protection?

Btw Thanks Saad for clearing it out.

Yes.
No problem. We're here to help.

i don't think group 1 metals are such a good idea. Group 1 metals are extremely reactive even in air

Hope we all get A*s .

Also, can anyone explain me esters as well as isomers in detail.

But you can use them. We don't use them is another thing. We commonly use Zinc.

I am just confused whether Zinc can be used in both the processes or not since it is a more reactive metal than Iron?

It can. In galvanization, you apply a COATING OF ZINC on the iron.

yup it can be both ways

 

[farhan141]

I haven't come across sacrificial protection as of now. Which book do u use?

Thank you both of u nerds

 

[Saad Mughal]

Thank you both of u nerds

usama321, Don't you hate it when people do this?

 

[Saad Mughal]

Well, now, its time for Past Papers.
I used Fundamental Chemistry.

yeah and even more when they don't even bother hitting the like button

 

[usama321]

m off to sleep,

I don't want likes, but just calling someone who helps you a nerd is bizarre.

So early? Khairiyat? Chemistry nai jaan leli?

Which reagent could be used to distinguish between dilute nitric acid and dilute hydrochloric
acid?
A aqueous barium chloride
B aqueous silver nitrate
C aqueous sodium hydroxide
D copper(II) carbonate

Explain please?:s

LOL B is the answer
as for Nitric acid it will give no reaction and for HCl will give White ppt of silver chloride
