Part C Acid-Base Reactions pKa

Each acid (H—Z) has an experimentally determined Ka value. pKa is a measure of the energy difference between the conjugate acid (H—Z) and the conjugate base (Z ) in the solvent, water. This means Ka is an estimate of... [Pg.45]

(E) In Table 4.5, review which structure is the conjugate acid and which structure is the conjugate base in each colunrn. [Pg.45]

(E) How much energy is released when the lone pair on H2N makes a bond to an H (Give the value and sign of the energy change in p/C units.) [Pg.45]

A student answers -9 to the previous question. What mistake did this student make [Pg.45]

Find the one curved arrow on Table 4.5. What is the energy change associated with this arrow [Pg.46]
