Calculate the pH of a solution prepared by diluting 0.0015L of a 0.100 mol/L nitric acid solution with 0.5L of water.

Question

*C1×V1=C2×V2
C2=0.3MOL/L
Do we use this concentration to find the pH

Answer 1

Your use of c1v1 = c2v2 is ok but I don't think you punched in the right numbers. Or set it up wrong.
0.1 x 0.0015 = C2 x 0.5
C2 = ?
And yes, you use C2 to solve for pH. I obtained about 3.5(estimated)
