Chemistry Unit 9

• If an ion in acid ends w "ide"---> acid name becomes....

  Hydro (anion root) ic acid

  ex: HF--> Fluoride, ends in ide... so gets replaces with ic becoming hydrofluoric
• Bromide (HBr) using acid naming

  hydrobromic acid
• In anion name ends w "ate"--> acid name becomes...

  (anion root) ic acid

  ex: H2Cr2O7---> dichromate, ends in ate... so it becomes dichromic acid
• Name bromate using acid naming

  Bromic acid
• If anion name ends w "ite" ---> acid name becomes....

  (anion root) uous

  ex: HClO2--> chlorite, ends in "ite"---> so it becomes chlorous acid
• Hypochlorite (HClO) using anion naming rules

  hypochloruous acid
• Anion


  an atom that has more electrons than protons- negative charge
• Bronsted-Lowry


  Acid is proton (H+) donor while base is a proton acceptor.
• conjugate


  compound formed by joining of two or more chemical compounds
• Proton (H+) donor


  acid
• proton (H+) acceptor


  base
• product formed when acid looses H+

  conjugate base
• product formed when base gains H+

  conjugate acid
• pH=


  -log [H30+]
• POH=


  -log [OH-]
• pH+POH=


  14.00
• [H30]*[OH-]=


  1.0*10^-14
• Antilog


  10^___
• Amphoteric


  Both acid and base
• pH


  Potential of hydrogen /measure of how acidic or basic a substance is
• pH 7>


  Acid
• ph 7< 


  Basic
• pH 7 


  neutral
• pH scale range 


  0-14
• Arrhenius def of Acid:

  substance that increases concentration of hydrogen ions (H+) when dissolved in water (H20)
• Arrhenius def of base:

  compound that increases concentration of hydroxide (OH-) in aqueous solution
• Logramithmic scales


  method of displaying data in multiples of 10
• If hydrogen ions go up the hydroxide ions in Arrhenius would..?

  Go down
• If you combined strongest acid and base they would...?

  neutralize each other leading to the acidic and basic properties no longer being present
• How would you determine the strongest acid/base..?

  through dissolution
• Red or pink cabbage juice indicates it is a...

  acid
• Yellow or green cabbage juice indicates it is a ..

  base
• pronated


  adding proton (H+) to atom/molecule/ion to form conjugate acid
• depronated


  removal of proton (H+) from Bronsted Lowry acid
• Acid-base indicator shows...


  whether a solution is acidic, neutral or alkaline
• When do acid- base indicators change?

  When they become pronated or depronated
• Taste of acid


  sour
• Taste of base


  bitter
• Slippery feel 


  base
• Both acid and base conduct electricity
