Titration

• Indicators are substances used to detect the endpoint of a titration by changing color at specific pH values.
• The indicator is added to the solution being titrated, which changes color as the reaction progresses towards neutralization.
• Titration


  A lab technique where a volume of a known concentration (of acid or base) is used to determine the concentration of another solution
• Standard solution


  Solution of known concentration
• Indicator must be used in titration
• Endpoint/equivalence point


  Shows when there is neutralization (ratio of acid-base is "equal")
• Acids & bases do not always react in a ratio of one H+ to one OH-
• Use this equation when there's more than one H+ or OH+


  (#A)(MA)(VA) = (#B)(MB)(VB)
• TITRATION EQUATION - On Table T

  (MA)(VA)=(MB)(VB)
• #A- # of H+ in acid molecule

  * You get this info from molecule in the question.
• #B- # of OH- in base molecule

  * You get this info from molecule in the question.
• potassium hydroxide

• Hydrochloric acid
