I have a copper (II) sulphate, lactic acid, nitric acid solution (100 mL) with pH 2.3. I want to get this solution to pH 12, but I don't want to significantly increase the amount of solution. If say, I wanted to use 10 mL of NaOH to raise the pH to pH 12 what concentration NaOH would I need? I'm assuming the concentration would need to be extremely high, would the amount of NaOH needed even dissolve in 10 mL of DI? Is there a simple way to make this calculation?
If someone could point me in the right direction it would be appreciated.
