text: Figure 11 shows such data, and focusing on magnesium, it can be seen that with a magnesium concentration of 1280 ppm (the concentration in seawater), magnesium becomes insoluble as magnesium hydroxide at pH values above about pH 9.2 (that is, the solubility above pH 9.2 is below 1280 ppm, or below 1.3 x 10 3 ppm).
