CHEM 105 Lecture 17: Strength and Buffers
Document Summary
If the acid is weak, you need to put two arrows because the reaction is so weak that it can go back and forth in the solution. The strength is related to its hydronium ion concentration. The strength is related to its hydroxide ion concentration. Slippery ph of acids: ph literally stands for the power of hydronium ph = -log (h3o+), where the concentration is molar ph < 7 is acidic; ph= 7 is neutral; ph > 7 is basic. Ex: 0. 1 m hcl = 1. 0 x 10^(-1) m hcl; so ph = 1. Typical abg ranges are: ph= 7. 35 to 7. 45 ph too low gives heart problems; ph too high fives muscular problems. Paco2= 4. 7 - 6. 0 kpa (same as 35-45 mm hg) Hco3- = 22-26 meq/l, same as 22-66 mm. If your kidneys are damaged, they are less able to add hco3- to your blood stream.
