of 9 > Determine the dissociation constants for the acids. Express the answers in proper scientific notation where appropriate. Acid A: pK, - 6.0 K, Acid B: pK, = 9.60 K. = Acid C: pK, = -2.0 K.- Which is the strongest acid?
1.) Determine the dissociation constants for the acids. Express the answers in proper scientific notation where appropriate. Acid A: p?a=5.0 ?a= Acid B: p?a=9.10 ?a= Acid C: p?a=−2.0 ?a= Which is the strongest acid? 2.) The ?bKb for an amine is 7.416×10−5.7.416×10−5. What percentage of the amine is protonated if the pH of a solution of the amine is 9.1309.130? Assume that all OH−OH− came from the reaction of B with H2O.H2O. percentage protonated

pH of a Strong Acid and a Strong Base 11 of 16 > II Review Constants Periodic Table pH is a logarithmic scale used to indicate the hydrogen ion concentration, H'], of a solution: pH = -log[H] The temperature for each solution is carried out at approximately 297 K where Ky = 1.00 x 10-14 Part A Due to the autoionization of water, in any aqueous solution, the hydrogen ion concentration and the hydroxide ion concentration, OH-], are related to...
M Review Constants Part A - Determine the equivalent inductance to the right of terminals b and e, including L4 Learning Goal: To reduce series-parallel combinations of inductors or capacitors to an equivalent inductance or capacitance. Inductors in series and parallel combine like resistors in series and parallel. It is possible to use Kirchhoffs current law to find the current through the equivalent inductance. Moreover, capacitors in series combine like resistors in parallel and vice versa. It is possible to...
