Presentation Transcript

  1. pH and Indicators May 7th, 2013

  2. pH pH = measurement of [H+] in solution Logarithmic Scale pH of 1 is very acidic pH of 14 is very basic pH of 7 is neutral pH = -(log [H+]) [H+] = 10-pH

  3. pOH and Calculations • pOH= measurement of [OH-] in solution • pOH = -(log [OH-]) • pH + pOH = 14 • [H+] X [OH-] = 1 x 10-14 = kw

  4. Measuring pH • Indicators • Chemical that changes color when exposed to acidic, neutral and basic substances

  5. Make an Indicator! • Red cabbage will show, by color change, the approximate pH of a solution
