Presentation Transcript

  1. 4/5/13 Bell Work Have on your desk: class notebook, reference material, pen or pencil, highlighter Answer the following in your class notebook: • What is the pH if the pOH is 12? ______ • What is the pH if the [H+] is 1.0 x 10-5 M? _______ • Complete the following reaction: HCl + NaOH ______________ + ____________

  2. Acids & Bases Indicators Naming

  3. Indicators • Universal Indicator- • Can measure a range of pH’s • Compare color with chart • Blue litmus paper – • Turns red in acidic conditions • Red litmus paper – • Turns blue in basic conditions

  4. Let’s see if this works . . . • Sample 1: ____________ • Sample 2: ____________ • Sample 3: ____________ • Sample 4: ____________

  5. Naming ACIDS • Binary Acids • 2 elements • How we name this compound • 2 words: Hydro + element root + icacid _________________ ______ HCl

  6. Naming ACIDS • Binary Acids • 2 elements • Practice: Hydro + element root + icacid _________________ ______ HI

  7. Naming ACIDS • Ternary Acids • More than 2 elements • NO hydro • How we name this compound • 2 words: polyatomic root + (IC/OUS) acid If root ends in ate, use IC If root ends in ite, use OUS If root ends in ide, use IC _________________ ______ H2CO3

  8. Naming ACIDS • Ternary Acids • More than 2 elements • NO hydro • How we name this compound • 2 words: polyatomic root + (IC/OUS) acid If root ends in ate, use IC If root ends in ite, use OUS If root ends in ide, use IC _________________ ______ If you have SO42- use root: sulfur___ If you have PO43- use root: phosphor___ H2CO3

  9. Naming ACIDS • Ternary Acids • More than 2 elements • NO hydro • How we name this compound • 2 words: polyatomic root + (IC/OUS) acid If root ends in ate, use IC If root ends in ite, use OUS If root ends in ide, use IC _________________ ______ H2SO4

  10. Naming BASES • Two words: CATIONANION • Cation: • Don’t forget … you may need a Roman numeral if it’s a transition metal! • Anion: • Use its name Example: LiOH _________ ______

  11. Naming BASES • Two words: CATIONANION • Cation: • Don’t forget … you may need a Roman numeral if it’s a transition metal! • Anion: • Use its name Example: BaOH _________ ______

  12. Practice Name the following acids: • H3PO4 _______________________________ • HBr _________________________________ Name the following bases: • Ca(OH)2 ______________________________ • NH4OH ______________________________
