What is the pH of a nitric acid solution needed to etch a copper plate in which you must have 3.12×10^-5 moles
What is the pH of a nitric acid solution needed to etch a copper plate in which you must have 3.12×10^-5 moles of hydronium ions per mililiter of solution?

3.12 x 10^-5 mol / mL x 1000 mL / 1 L = 3.12 x 10^-2 M
pH = – log 3.12 x 10^-2 = 1.50
