Concept Introduction:
Cations are named using the name of the element that is followed by the word “ion”. In case of the elements that has more than one cation possibility, the oxidation number is shown using Roman numeral in parenthesis.
Anions are named by adding suffix –ide that is followed by the word “ion”. This is applicable for monoatomic anions. If the anion is a polyatomic one that contains oxygen atom, it is known as oxoanions and it is named by adding suffix –ate to the name of the element which is the stem.
- Ions that have more number of oxygen atoms are named using the suffix –ate.
- Ions that have less number of oxygen atoms are named using the suffix –ite.
If an oxoanion contains halogen atom, then the name of the oxoanion is named considering the number of oxygen atoms present in it.
- If the oxoanion contains less number of oxygen atoms with halogen atom, then prefix hypo- is added to the –ite form of the name of oxoanion.
- If the oxoanion contains more number of oxygen atoms with halogen atom, then prefix per- is added to the –ate form of the name of oxoanion.
If the polyatomic anion contains hydrogen atom, then it is named by considering the number of hydrogen atoms present in it. If one hydrogen atom is present, the anion is named beginning with “hydrogen” and if two hydrogen atoms are present, then the anion is named beginning with “dihydrogen”.

- 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?
