A 1-mL solution of 0.1 M NaOH is diluted to 1 L at 25°C.What is the pH of the resulting solution?

First, we need to calculate the concentration of the diluted solution:
M1V1 = M2V2
(0.1 M)(1 mL) = (M2)(1000 mL)
M2 = 0.0001 M

Now, we can use the formula for the pH of a basic solution:
pOH = -log[OH-] = -log(0.0001) = 4
pH = 14 - pOH = 14 - 4 = 10

Therefore, the pH of the resulting solution is 10 (choice C).
