WebApr 5, 2024 · answered. What is the pH of a 1x10-2 M NaOH solution? a. pH = 2. b.pH = 12. c.pH = 1x10-2. d. pH = 1x10-12. Oe. None of the above. WebJul 30, 2016 · Explanation: The answer can be obtained one of two ways: Use the auto-ionization constant of water equation, Kw: All you would have to do is rearrange the equation to solve for [OH −] by dividing both sides of the equation by [H 3O+]: [OH −] = 1.0 × 10−14 [H 3O+] Plug in the known concentration of H 3O+ ions: [OH −] = 1.0 × 10−14 1.0 ×10−6 WebThe pH equation is still the same: , but you need to use the acid dissociation constant (Ka) to find [H+]. The formula for Ka is: where: – concentration of H+ ions – concentration of conjugate base ions – concentration of undissociated acid molecules for a reaction This formula describes the equilibrium. phlegm in throat when i wake up
