Problem How would you prepare 5.0 L of a 1.5 M solution of glucose? First chemical formula for glucose is ? C 6 H 12 O 6
Work Find the molar mass of glucose Molar mass of glucose = 180.18 g C 6 H 12 O 6
Work Cont 1.5 mol C 6 H 12 O 6 180.18 g C 6 H 12 O 6 5.0 L solution 1 L solution 1 mol C 6 H 12 O 6 Answer= 1351.35 g C 6 H 12 O 6 Write as Put 1351.35 g C 6 H 12 O 6 in a 5.0 L container and add enough water to get 5.0 L.
Properties of Acids and Bases Although taste is not a safe way to classify acids and bases, you probably are familiar with the sour taste of acids.
Acid Contain hydrogen ion (H+) pH < 7 Taste sour Electrolyte Reacts with metals that are more reactive than H+. [acidus is latin for sour]
Examples of Acids Lemon juice Vinegar (Acetic Acid) Hydrochloric Acid
Metal Activity Chart Li K Ba Sr Ca Na Mg Al Mn Zn Cr Most Active Fe Cd Co Ni Sn Pb H Cu Bi Sb Hg Ag Pt Au Least Active
ACID-BASE THEORIES The most general theory for common aqueous acids and bases is the BRØNSTED - LOWRY theoryThe most general theory for common aqueous acids and bases is the BRØNSTED - LOWRY theory ACIDS DONATE H + IONSACIDS DONATE H + IONS BASES ACCEPT H + IONSBASES ACCEPT H + IONS
Bronsted - Lowrey Came up with a theory that states an acid is a H + donor, a base as a H + acceptor.
