Calculate the percent composition by mass of the following compounds that are important starting materials for synthetic polymers: a. C3H4O2 (acrylic acid, from which acrylic plastics are made) b. C4H6O2 (methyl acrylate, from which Plexiglas is made) c. C3H3N (acrylonitrile, from which Orlon is made)
Week 7, Prof. Cracolice, Chem 143 Chapter 58: How are Characteristics of a Buffer Solution Determined 3/11/16 58.1 How are Characteristics of a Buffer Solution Determined Reactions are catalyzed by enzymes, effectiveness of most enzymes is very sensitive to pH What Determines the pH of a Buffer WK−¿ + HWk o [H O3]=K x a ¿ ¿ o K ia constant, concentration of hydronium ions depends entirely and proportional to the ratio of acid concentration to the base concertation o Ratio constitutes fixed pH determining ratio of desired pH o Helps if K and desired hydronium concentration is known
