Document Summary

Acids and bases appear in many aspects of our lives. One of the most produced chemicals in the world. Baking soda nahco3 (adenine, guanine, cytosine and thymine) In acid-base rxn, a proton is transferred from the acid to the base. Ha + b bh+ + conjugate acid conjugate base base acid. Note that water can be either an acid or a base in a. H3o+ is called the hydronium ion is equivalent to h+ Water can be an acid or a base. H2o + h2o h3o+ (aq) + oh (aq) Or simplified h2o (l) h+ (aq) + oh (aq) [h+] = [oh ] or [h+] = 1. 0 x 10 m = [oh ] In tap water, say [h+] = 3. 0 x 10 . In aqueous solutions at 25 c (room t in general) When [h+] > 10 7 m solution is acidic. When [h+] < 10 7 m solution is basic.
