Hydrochloric Acid 2N - Easy instructions - Not for volumetric titrations unless standardised first.
info HYD 2N

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 wa ter NEVER wat er into acid- it "spits"
NB 32% hydro chloric 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
