Concept explainers
(a)
Interpretation:
K+ should be combined with SO32- in order to derive an ionic compound with zero net charge.
Concept introduction:
An ionic compound is derived by forming an ionic bond between 2 oppositely charged ions. The cations & anions should be combined in a ratio that the net charge of the compound should be zero.
(b)
Interpretation:
Ba2+ should be combined with SO32- in order to derive an ionic compound with zero net charge.
Concept introduction:
An ionic compound is derived by forming an ionic bond between 2 oppositely charged ions. The cations & anions should be combined in a ratio that the net charge of the compound should be zero. If the charges are same in both, the combining ratio is 1: 1.
(c)
Interpretation:
Al3+ should be combined with SO32- in order to derive an ionic compound with zero net charge.
Concept introduction:
An ionic compound is derived by forming an ionic bond between 2 oppositely charged ions. The cations & anions should be combined in a ratio that the net charge of the compound should be zero. To obtain this charge neutrality multiple numbers of cations & anions can be combined.
(d)
Interpretation:
Zn2+ should be combined with SO32- in order to derive an ionic compound with zero net charge.
Concept introduction:
An ionic compound is derived by forming an ionic bond between 2 oppositely charged ions. This bond formation occurs through electrostatic attraction forces between 2 opposite charges. The cations & anions should be combined in a ratio that the net charge of the compound should be zero.

- Use the literature Ka value of the acetic acid, and the data below to answer these questions. Note: You will not use the experimental titration graphs to answer the questions that follow. Group #1: Buffer pH = 4.35 Group #2: Buffer pH = 4.70 Group #3: Buffer pH = 5.00 Group #4: Buffer pH = 5.30 Use the Henderson-Hasselbalch equation, the buffer pH provided and the literature pKa value of acetic acid to perform the following: a) calculate the ratios of [acetate]/[acetic acid] for each of the 4 groups buffer solutions above. b) using the calculated ratios, which group solution will provide the best optimal buffer (Hint: what [acetate]/[acetic acid] ratio value is expected for an optimal buffer?) c) explain your choicearrow_forwardHow would you prepare 1 liter of a 50 mM Phosphate buffer at pH 7.5 beginning with K3PO4 and 1 M HCl or 1 M NaOH?
