Document Summary
Acids produce h+ ions: hcl h+ and cl- Bases produce hydroxide ions: naoh -> Salts produce neither: nacl -> na + and cl- ph a review ph = log [1/h+] = -log [h+] ph scale. The difference between ph 3 and ph 4 is a 10 fold difference in the concentration of h+ [h+] = [oh-] ph + poh = 14. Like in terms of polarity: polar solutes dissolve in polar solvents, nonpolar solutes dissolve in non-polar solvents. Hydrophilic substances interact with water molecules (both water and substances are polar) Except for water, all are built on carbon skeleton. Look at table 4. 9 (functional groups of organic compounds) Carbonyl - aldehydes (terminal carbon) and ketones. Synthesis of polymers covalent bond formation between monomer units (making them) Proceeds with the removal of a water molecule. Figure 5. 2 (the synthesis and breakdown of polymers) Breakdown of polymers breaking the covalent linkage between monomer units.
