  1. TOPIC 10 – ACIDS, BASES, & SALTS DO NOW: ANSWER QUESTIONS IN M.C. PACKET PG. 1

  2. Behavior of many acids and bases can be explained by the Arrhenius theory • Arrhenius acids and bases are electrolytes • An electrolyte is a substance which, when dissolved in water, forms a solution capable of conducting electricity The ability to conduct electricity depends on the concentration TOPIC 10 – REGENTS REVIEW

  3. Arrhenius acids yield H+ (H3O+) ion as the only positive ion in solution • H+ (aq) ions may also be written as H3O+ • Arrhenius bases yield OH-ions as the only negative ion in solution • Organic compounds with OH- are not bases • Ammonia (NH3) is a base TOPIC 10 – REGENTS REVIEW

  4. In neutralization reactions an Arrhenius acid react with an Arrhenius base to form HOH and a salt • The net ionic equation for all neutralization reactions is the same: H+(aq) + OH-(aq)  H2O(l) • Titrationis a lab process in which a volume of a solution of known concentration is used to determine the concentration of another solution. It is a practical application of a neutralization reaction TOPIC 10 – REGENTS REVIEW

  5. Alternate theory state that an acid is an H+donorand a base is an H+acceptor • The acidity or alkalinity of a solution can be measured by pH • Low pH indicates a higher concentration of H+ ions than OH-ions • High pH indicates a lower concentration of H+ ions that OH- ions • A neutral pH (7) indicated an equal concentration of both • Pure water has a neutral pH TOPIC 10 – REGENTS REVIEW

  6. On the pH scale, each decrease of one pH unit represents a tenfold increase in H+ ion concentration TOPIC 10 – REGENTS REVIEW
