full procedure of making normal/molar HCL soluton?

Question

main problem is that HCL is a liquid & we need gm four normal molar solution

Answer 1

Easy, the molecular weight of HCl is 36.461 gr per mole.

If your trying to reach 4 molar solution then you need 4 x 36.461g HCL diluted to 1 liter. you need 145.844g HCl in the liter

But since your probably using 32-38 % HCl (actual amount might be on the bottle) you need to multiply you'll need to adjust for inactives by assuming your active molar mass is ~35% of 36.461 or 12.761g

in order to make 1 liter of 4 molar solution you'll need 416.71g

36.461/12.761 * 145.844 = 416.71

assuming it is 35 % active.

You should always standardize your solution after mixing to determine final activity!!!!!
