Question 1. If the hydronium ion concentration, [H3 style=”color:rgb(17,17,17);”>O+], in a solution is 5.6×10−10 M, what is the hydroxide ion concentration, [OH−], and the pH of the solution? [OH−] = 1.8×109 M, pH = 4.75 [OH−] = 5.6×10−10 M, pH = 10.56 [OH−] = 1.0×10−7 M, pH = 5.60 [OH−] = 4.4×10−4 M, pH = 9.25 [OH−] = 1.8×10−5 M, pH = 9.25
