Answer to Question #206596 in Chemistry for Chris bridges

Question

Calculate the hydronium ion concentration of a solution with a pH of -1.07

Answer 1

pH = −log[H₃O⁺] = 1.07

log[H₃O⁺] = −1.07

[H₃O⁺] = 10^–1.07 or [H₃O⁺] = antilog of −1.07

[H₃O⁺] = 0.085 M

(On a calculator take the antilog, or the “inverse” log, of −1.07, or calculate 10^–1.07.)
