Question

I need to make a reagent and the recipe says 60% hcl but how do I dilute my concentrated 37% hcl

Answer 1

You can not make 60% by diluting 37% , Think !
Perhaps you have it backwards?

Answer 2

Hello Damon, as you see I am not at all familiar with chemistry, ok i need to restore firearms serial number using a reagent comprising 60% hcl 40% distilled water I just don't know how to safely make this solution, is it as it appears meaning 60 ml of hcl with 4ml distilled water

Answer 3

If you start with a bottle containing 37% HCl You can not get to 60% HCl
However perhaps it means
use 60 mL of your 37% bottle and 40 mL of the pure water to make a total of 100 mL of the mix. That will result in a weaker acid than what was in the original bottle.
