Webb14 okt. 2024 · pOH = pKb + log [NH4Cl]/ [NH3] To find the pKb from the Kb, simply take the negative log of the Kb. -log1.8x10-5 = 4.745 pOH = 4.745 + log [0.24]/ [0.181] pOH = 4.745 + log 1.326 pOH = 4.745 + 0.123 = 4.868 Then to find the pH, we can use pH + pOH = 14 and pH = 14 - pOH pH = 14.00 - 4.868 pH = 9.13 Upvote • 0 Downvote Add comment Report WebbPredict whether a precipitate will form if you mix 75.0 mL of a NaOH solution with [OH-] = 2.6 x 10-3 M with 125.0 mL of a 0.018 M MgCl2 solution.
