  1. Self-Ionization of Water A. In the _________________ of water, a ________ molecules produce a _____________ ion, H1+, and a ____________ ion, OH1-. self-ionization water hydrogen hydroxide

  2. Self-Ionization of Water 1. Conductivity measurements show that concentrations of H1+ and OH1- in pure water are each only __________ of water at 25°C. 1.0x10-7M

  3. Self-Ionization of Water concentration 2. To represent _________________ in moles per liter (M), the formula of the particular ion is enclosed in brackets, [ ]. Examples: ________ and _______. [H1+] [OH1-]

  4. Self-Ionization of Water 1.0x10-7M 3. In water at 25°C, [H1+]=___________ and [OH1-] =___________. 1.0x10-7M

  5. Self-Ionization of Water

  6. Self-Ionization of Water product 4. The mathematical __________ of [H1+] and [OH1-] remains constant in water and aqueous solutions at constant _______________. This is known as the ____________ ___________ of water, Kw. Kw = [H1+] [OH1-] temperature ionization constant

  7. Self-Ionization of Water Kw = [H1+] [OH1-]= (1.0x10-7M) (1.0x10-7M) = __________ 1.0x10-14

  8. Self-Ionization of Water 6. It is important to note that Kw increases with increasing _______________. temperature

  9. Self-Ionization of Water A. Important relationships involving acidic, neutral, and basic solutions are summarized below: Acidic: [H1+] ____ [OH1-] Neutral: [H1+] ____ [OH1-] Basic: [H1+] ____ [OH1-] > = <

  10. Self-Ionization of Water kw A. Use _____ to calculate concentration of unknown ion.

  11. Self-Ionization of Water Kw B. Notice that in order for _____ to remain constant an ___________ in either [H1+] or [OH1-] causes a ___________ in the other ion. increase decrease
