You have samples of two different compounds, CH3(CH2)3C(CH3)2OH and CH3(CH2)6OH. Which one of these tests can be used to distinguish between the pair of compounds shown above? 1. Br2 in CH3CCl3 2. NaHCO3 solution 3. heptane/water solubility 4. dilute HCl 5. H2CrO4
What is the change in the measurement of the potential if a solution of 1.00x10-3 M NaF is exchanged for another solution of 1.00x10-4 M NaF?
Based on the Henderson-Hassalbach equation how many mmols of Tris-HCl are there in a 100 mL of a 100 mM Tris-HCl buffer solution at pH 8.1? Note that the 100 mM refers to the sum of Tris and Tris-HCl concentrations.
Calculate the expected pH values of the buffer systems from the experiments (a, b, c, d) using the Henderson-Hasselbalch equation (pH= pKa + log [A-] ). Use for pKa values: carbonic acid= 6.37 and acetic acid= 4.75.
