[H+] = 10 raised to the -pH, or 10 raised to -3, which equals .001. Then Ka = [H+] squared / Molarity of the solution, which equals 1.72 E(-6).

Why is the second ionization higher than the first ionization?
Second ionization coefficient is NOT higher than the first
ionization coefficient. Matter a fact, when compared to the first
