Concept explainers
a)
Interpretation:
The oxidation state of oxygen in each oxide and the oxidation state of the other element has to be identified.
Concept introduction:
Oxidation state:
As per the IUPAC definition, the charge of the atom is the oxidation state of an atom after ionic approximation of its heteronuclear bonds or it is a number assigned to an atom or an element which represents the number of electrons lost or gained.
b)
Interpretation:
The bonding nature of metal oxides has to be identified.
Concept introduction:
Covalent bond:
The bond which involves sharing of electrons between the atoms present in the molecule
Ionic bond:
The bond which involves transfer of electrons between the atoms present in the molecule
c)
Interpretation:
The acidic or basic nature of the oxides has to be identified.
Concept introduction:
Acid:
The substance which is capable of accepting a pair of nonbonding electrons and forms covalent bond
Base:
The substance which is capable of donating a pair of nonbonding electrons
d)
Interpretation:
The identity of the metal in the compounds (1) and (2) has to be identified.
Concept introduction:
Oxidation state:
As per the IUPAC definition, the charge of the atom is the oxidation state of an atom after ionic approximation of its heteronuclear bonds or it is a number assigned to an atom or an element which represents the number of electrons lost or gained.

- 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? Please help and show calculations. Thank youarrow_forwardDraw the four most importantcontributing structures of the cation intermediate thatforms in the electrophilic chlorination of phenol,(C6H5OH) to form p-chlorophenol. Put a circle aroundthe best one. Can you please each step and also how you would approach a similar problem. Thank you!arrow_forward
- A 100mM lactic acid/lactate buffer was found to have a lactate to lactic acid ratio of 2 and a pH of 4.2. What is the pKa of lactic acid? Can you please help show the calculations?arrow_forwardUsing line angle formulas, draw thestructures of and name four alkanes that have total of 7carbons, one of which is tertiary.Please explain this in detail and can you also explain how to approach a similar problem like this as well?arrow_forwardUsing dashed line wedge projections drawthe indicated compounds and indicate whether thecompound you have drawn is R or S.(a) The two enantiomers of 2-chlorobutane.
