Hi everyone,
My silver bath is ph 3, is that to acid ? How do I raise it to 4-6?
Can I use sodium hydroxide?
Hmmmm....
Thanks!

I agree--test it first before adjusting the pH. My silver bath is pH 4 and it works fine. The more acidic the silver bath, the less sensitive the plate--but unless your exposures seem abnormal, it may not be an issue. One simple way to raise the pH is to add a volume of non-acidified silver nitrate. I usually see Calcium Carbonate or Sodium Carbonate recommended as a neutralizing agent--be sure to sun and filter after neutralizing.
How would I lower the PH ? I have nitric acid 7% to increase. hanks
I have never adjusted or cared about the silver bath PH for over 10 years of shooting plates. Just shoot.
You can work with pH 3, it will just be less sensitive than a higher pH bath
