Hydrochloric Acid 1N - Easy instructions - Not for volumetric titrations unless standardised first.
info HYD 1N

Making hydro chloric acid  1,2,3,4,5 or 6N Hydro chloric acid  
These are all rough percentages and are not for    
volumetric titrations without standardising.      
                 
NB 32% HCl = 8.8N ; 36.5% (37%) = 10N      
                 
36.5g HCL in 1L = 3.65% = 1N          
                 
Calculations below are to make 1L        
ALWAYS add /pour acid into wat er NEVER wa ter into acid- it "spits"
NB 32% hydrochloric acid has 320 g per 1000g ; 37% HCL has 370g/Kg    
from 32% HCL 1N 2N 3N 4N 5N 6N    
water 886g 772g 658g 544g 430g 316g    
32% HCl 114g 228g 342g 456g 570g 684g    
                 
From 37% HCL                
Water 901.5g 803g 704.5g 606g 507.5g 409g    
37% HCL 98.5g 197g 295.5g 394g 492.5g 591g    

Allow to cool.

If doing titrations, standardise before use.

 

Calculation based on Hydrochloric acid 32% = 320g per 1000g

so 114g of the solution contains 36.5g HCL

Molecular weight of HCl = 36.5

36.5/36.5 =  1N
