Gold bearing solution concentration question

[Noxx]

Hello guys !
I have a question about HCl.
Here's the context: in the DBC (Dibutyl Carbitol) patent, they say that the gold bearing solution should be between 0.5-1.75N.

If I remember correctly, one Normal is one Mol/L. ?

If so, how do I know what's the HCl concentration of my solution ?

I dissolved 7.9 grams of gold in 30mL of HCl (30%) and 10mL of nitric acid.
Then I evaporated to remove any nitric remaining.

The only solution I see is to evaporate the solution to a syrupy constancy , add water, then repeat to get rid of the HCl and the nitric acid. Finally, I would add a calculated amount of HCl to the gold chloride solution to reach 1.0N

BTW, I do not own any pH meters so forget about calculating the H+ ions concentration

Thanks for any inputs.

The more I think about it, the more I see the evaporation process to be the only way to get it. Titration of my solution would be useless as I would ruin it.
Since, gold chloride (III) is soluble in water (68g/L). It is possible to get a solution which contains no more acids.

I'll let you know of my results.
