Presentation Transcript

  1. Electrolytes

  2. Definition • Any substance in an aqueous solution which contains ions (charged particles which are + or -). • Ions are conductors of electricity in aqueous solutions. Electrolytes

  3. Definition Electrolytes

  4. Electrolyte Categories • Acids • ‒ Turns blue litmus paper red. • ‒ Can be good conductors (HCl & HNO3). • Bases • ‒ Turns red litmus paper blue. • ‒ Can be good conductors (NaOH). • Salts • ‒ No effect on litmus paper. • ‒ Can be good conductors (NaCl, HgCl2). Electrolytes

  5. pH Strength of Acids & Bases Acid Base

  6. Molecular Dissolution • A substance’s molecules remain intact when in contact with an aqueous solution. • This contact creates a uniform composition of molecules. • e.g. Sugar + water = sugar water. Electrolytes

  7. Molecular Dissolution Electrolytes

  8. Ionic Dissociation • A substance breaks down and releases charged ions (+ or – particles) when mixed in an H2O solution. • The solution conducts electricity and is neutral overall (it contains an equal number of + and – particles). • Positive ions: Na+, H+, Li+, … • Negative ions: Cl-, NO3-, SO4-, … • * Ionic solution conduct electricity.
