Hi. I'm new here. All I know is what I've been reading in books. Any tips on concentrating HCl to 37%? I'm studying titration now and soon my plan is to boil my solution of 18% HCl and check it via titration until it's ready. This will be a long process. I was just wondering if there was a quick recipe lying around or something. Thanks.
