Lecture 3 pH definition acid: R-H -> R- + H+, CH3-COOH, HCl base: R + H+ -> RH+, NaOH measuring concentration of compounds mole = to mol weight H2 mw = 2, 1 mole = 2 g CH3-CH2-OH mw = 46 (2 C x 12, 1 O x 16, 6 H x 1), 1 mole = 46 g 1Molar solution = 1 mole/g calculating molarity of solutions beer = 6% EtOH = ~60 g/L = 1.3 M DWI = 0.8% EtOH = ~ 8 g/L = 0.17 M measure molarity of H+ to determine acidity water = 10-7M of H+ (and same of OH- in this case) 1M HCl = 1M H+ 1M NaOH = 10-14M H+ -log10[H+] = pH , ranges from 1 to 14 -log10(10-7) = pH 7 -log10(10-3) = pH 3 Carbohydrates source of energy, building blocks of structure and storage polymers monosaccharides: one-sugar, glucose coh-coh-coh-coh-coh-ch=o == coh-c(ring)-o-c(ring) <-ring formation common sugars exist in 3 to 7 carbon chains: pentose for 5, hexose for 6 glycosidic linkage (a covalent bond) attaches two sugars: glucose + fructose function: storage (remove water by polymerization and packing); steamed rice;
