Document Summary
The most important relationship as well as the hardest to fully understand is that of conjugate acids and bases. Acid + base conj base + conj acid: the acid hf makes the conjugate base f . Hf + h2o h3o+ + f : the base h2o makes the conjugate acid h3o+ We say f is a conjugate base because it was produced from the acid hf and yet f acts as a base. Hf + : this tells us hf will produce h+ and whats left over must be f . + h2o +h2o: hf + h2o h3o+ + f , the second reaction we can nd by remembering h+ is really h3o+. Adding h2o to each side of the equation 1 produces equation 2. The second equation makes it easy to see that f is the conjugate base of hf. They donate protons: this tells us hco 3 will produce h+ and what"s left over must be co2 3.
