Document Summary
Maintenance of internal ionic composition - including ph -is critical for the structure and function of biomolecules. Control of ph is critical in biochemical experiments. Acid is a substance that can donate a proton. Base is a substance that can accept a proton o o o. Follows le chatelier"s principle because it is in equilibrium. o. Makes a conjugate acid [hb+] and conjugate base [a-] More acid = shifts right to conjugate side. Found by formula weight of water and density. D = 1. 0 g/ml, 1x10-7 m = ph7** All hcl is converted to h+ and cl- Polyprotic acids: more than one acid-base group ex. The pka"s of two closely associated acid- base groups are not independent - the closer they are, the greater the effect. o o. 2 qs on buffer ph and pka will be on the midterm! Easier to isolate and characterize than nucleic acids, polysaccharides o.
