Acids and Bases Equations

Acids and Bases Equations. Arrhenius Theory. The Arrhenius theory explains why adding base to an acid makes the acid less acidic and vice versa. H + ( produced from acid ) + OH - ( produced from base )  H 2 O This is called neutralization.

  1. Acids and Bases Equations

  2. Arrhenius Theory The Arrhenius theory explains why adding base to an acid makes the acid less acidic and vice versa. H+(produced from acid) + OH-(produced from base)  H2O This is called neutralization.

  3. The neutralization of an acid with a base will always produce water and a salt. Examples Acid Base Water Salt HCl + NaOH H2O + NaCl HBr + KOH  H2O + KBr

  4. Salts • What exactly is a salt? • Any ionic compound! • Formed during acids and bases reactions • Not all salts taste salty • NaCl is table salt and tastes salty • Pb(C2H3O2)2 tastes sweet and will give you lead poisoning

  5. Bronsted-Lowry Theory Using the Bronsted-Lowry Theory, we can see how a salt is formed even when OH- ions are not present. Acid Base Salt HCl + NaHCO3  H2CO3 + NaCl

  6. Key Points • You can recognize an acid base reaction by: • Recognizing H+ and OH- ions in the reactants • Recognizing an H+ ion act as a proton donor • A salt (ionic compound) will always form • Neutralization: When a base is added to an acid and vice versa • The pH will move closer to neutral (pH of 7) • Water is always formed • A salt is always formed
