Question

How to prepare 1n hcl solution in 100 ml?

Answer 1

ANSWER:- ANSWER IS GIVEN BELOW HOPE IT HELPS PLEASE MARK IT AS BRAINLIEST IF HELPS SO !.

EXPLANATION:-

Generally the HCl that we get from manufacturer is 37%. It's concentration is 12N. So, Using the formula N1V1= N2V2, you can make the 1N solution of desired quantity. For example 1N 100ml HCl solution, x is volume of 37% Hcl to be taken and diluted

12 X x = 1 X 100

x = 100/12

x= 8.3ml. 

So, you can mix 8.3 ml of conc. Hcl and 91.7 ml of dH2O to make 1 N 100ml of HCl.

Answer 2

Answer:

Explanation:

We know that normality of HCl is 12 N

Acc.to the formula

N1V1=N2V2

N1=12N

V1=?

V2=100ml

Substituting the values in the above formula we get.

12×V1=1×100

V1=8.33ml

So we add 8.33ml i 100L of water we get 1 Normal Hcl
