Assume that the buret contains ions, the flask contains ions, the volumes in the buret and the flask are identical, and the concentration of the acid in the buret is 1.00 M. If the entire volume of the buret is required for titration of the base in the flask, what is the concentration of base?
1) Suggest a reason why the starting material (trans-1,4-diphenyl-2-butene-1,4-dione) should be recrystallized prior to use in the photochemical isomerization of an alkene.
What is the pH at the equivalence point when 40.00 mL 0.100 propionic acid, CH3CH2COOH, Ka = 1.3 x 10-5, is titrated with 0.1000 M NaOH?
61.0 mL of a solution(1.60 M) is diluted to a volume of 208 mL. A portion of that solution(104-mL) is diluted using 121 mL of H 2 O. determine the final concentration?
Organic Reactions - Cyclopentadiene, Why is cyclopentadiene monomer more stable at higher temperatures although dicyclopentadiene (dimer) is more stable at lower temperatures?
