Example 1 Example 2 Find the log of 7.21 x 10-5. Find the antilog of – 8.375.= log(7.21 x 10-5) = 10(– 8.375)= – 4.142 = 4.22x10-9 Complete the following table by calculating the required quantities. Assume 100% dissociation for all particles.pH + pOH = 14 So...
What is the pH of a 4.0M solution of H2S? If the pH of a solution is 10, what is the hydroxide ion concentration? Assuming complete dissociation, what is the pH of a 0.005 m HCl solution? What is the hydroxide ion concentration for a soluti...
Write the correct acid or base dissociation equilibrium constant (example: Ka2 or Kb1) for each step. A)PO43- B)H3N+C(H2)CO Use the reaction between hydrochloric acid and water to explain the Bronsted-Lowry theory of acids and bases. Which one ...
Disruption of β-barrel results in dissociation of the tetramer into dimers in solution and decreased biotin carboxylase activity. Biotinylation of the BCCP domain further promotes BC1 and CTβ-CTα interactions to form an enzymatically active ACC, which converts acetyl-CoA to malonyl-CoA in vitro...
Lead (Pb2+) is among the most toxic heavy metals even in low concentration and cause toxicity to human’s health and other forms of life. It is released into the environment through different industrial activities. The biosorption of Pb2+ from aqueous so
