What is the normality of the concentrated hydrochloric acid?

Answer 1

Generally this concentration is 36.5 %. However cocentrations up to just over 40% are possible but require special pressure and cool temperature conditions because the vapor pressure of the hydrogen chloride (which is dissolved into water to make hydrochloric acid) is high enough to cause evaporation of the hydrogen chloride out of the solution which then reduces the concentration unless you have the pressure and temperature conditions.

Answer 2

In catalogs of chemicals you will find concentrations up to 50 % in water solution.

Answer 3

Generally 36,5 % but also possible in catalogs 5 %, 10 %, 50 % and any other.

Answer 4

A true limit between diluted and concentrated don't exist; a HCl solution with a concentration under 1 M can be considered diluted.

Answer 5

It's usually around 12.

Answer 6

For a 36,5 % water solution of HCl: 10 N.

Answer 7

15.7

Answer 8

Under 1.
