Define why alcohols have a higher boiling point as well as greater water solubility than haloalkanes of similar molar mass.
Explain why is the water solubility of t-butyl alcohol greater than that of n-butanol? Explain why does the water solubility of alcohols decrease as the chain length increases?
A beaker with 120 ml of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 8.40 ml of a 0.250 M HCl solution to the beaker. How much will the pH..
