pH of the solution for 0 .0333 M HNO 3 has to be calculated and the solution is acidic, basic or neutral also has to be identified. Concept introduction: The concentration of H 3 O + is calculating by using following formula, K w = K a × K b K w = [H 3 O + ][OH - ] = 1 .0 × 10 − 14 The Relationships Among pH, pOH, and pKw pH = - log (H 3 O + ) pOH = - log (OH − ) pK w = pH + pOH = 14 .00 The pH is a unit of measure which describe the degree of alkanity or acidity of a solution. pH = − log [ H + ] A solution may be acidic and basic depends on relative strength of anions as an acid or base. Anions and cations can be acidic, basic and netural. Acidic have pH < 7 , basic have pH > 7 and netural have pH=7 .

Concept introduction:
The concentration of H3O+ is calculating by using following formula,
Kw = Ka × Kb
Kw = [H3O+][OH-] = 1.0×10−14
The Relationships Among pH, pOH, and pKw
pH = -log(H3O+)pOH = -log(OH−)
pKw = pH + pOH = 14.00
The pH is a unit of measure which describe the degree of alkanity or acidity of a solution.
pH = −log[H+]
A solution may be acidic and basic depends on relative strength of anions as an acid or base. Anions and cations can be acidic, basic and netural. Acidic have pH < 7, basic have pH > 7 and netural have pH=7.

Interpretation Introduction
Interpretation:
pOH of the solution for 0.0347MKOH has to be calculated and the solution is acidic, basic or neutral also has to be identified.
Concept introduction:
The concentration of H3O+ is calculating by using following formula,
Kw = Ka × Kb
Kw = [H3O+][OH-] = 1.0×10−14
The Relationships Among pH, pOH, and pKw

pKw = pH + pOH = 14.00
The pH is a unit of measure which describe the degree of alkanity or acidity of a solution.
pH = −log[H+]
A solution may be acidic and basic depends on relative strength of anions as an acid or base. Anions and cations can be acidic, basic and netural. Acidic have pH < 7, basic have pH > 7 and netural have pH=7.
What spectral features allow you to differentiate the product from the starting material?
Use four separate paragraphs for each set of comparisons. You should have one paragraph each devoted to MS, HNMR, CNMR and IR.
2) For MS, the differing masses of molecular ions are a popular starting point. Including a unique fragmentation is important, too.
3) For HNMR, CNMR and IR state the peaks that are different and what makes them different (usually the presence or absence of certain groups). See if you can find two differences (in each set of IR, HNMR and CNMR spectra) due to the presence or absence of a functional group. Include peak locations. Alternatively, you can state a shift of a peak due to a change near a given functional group. Including peak locations for shifted peaks, as well as what these peaks are due to. Ideally, your focus should be on not just identifying the differences but explaining them in terms of functional group changes.
