You collect a 150 mL sample of lake water contaminated with HClO4. You take it back to your lab for analysis. You test the pH of the water sample with a pH probe and it is 4.5 You then titrate it with 0.05 M NaOH
a) What volume of NaOH do you need to neutralize the acid? (Hint: pH= -log(hydrogen concentration)
Like right now I have 4.5 = -log (x) and idk what to do lol. Firstly idk how I'd find 'x', and then once I find it... 'x' would also be the concentration of NaOH?
