Explanation of Solution
Given that volume of acid,
The titration reaction is
Where B represents cocaine and
When volume of acid added is
Molarity of cocaine is
Therefore,
Solving for ‘x’,
Then
When volume of acid added is
Thus the fraction of Cocaine titrated when
For protonated cocaine,
Substitute the values known to determine
When volume of acid added is
Thus the fraction of Cocaine titrated when
For protonated cocaine,
Substitute the values known to determine
When volume of acid added is
Thus the fraction of Cocaine titrated when
For protonated cocaine,
Substitute the values known to determine
When volume of acid added is
Thus the fraction of Cocaine titrated when
For protonated cocaine,
Substitute the values known to determine
When volume of acid added is
Thus the fraction of Cocaine titrated when
For protonated cocaine,
Substitute the values known to determine
When volume of acid added is
Thus the fraction of Cocaine titrated when
For protonated cocaine,
Substitute the values known to determine
When volume of acid added is
Thus the fraction of Cocaine titrated when
For protonated cocaine,
Substitute the values known to determine
When volume of acid added is
When volume of acid added is
Assume,
Solving for ‘x’,
Then
After reaching the equivalence point, continual addition of acid increases the concentration of acid so that we need to calculate
When volume of acid added is
Substitute the values known to determine
When volume of acid added is
Substitute the values known to determine
When volume of acid added is
Substitute the values known to determine

Quantitative Chemical Analysis
- The emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes.
