Final Answer:
The number of moles to be B) Calculate of citric acid are in the sample. (option b)
Step-by-step explanation:
In redox titrations, the number of moles of a substance in a sample can be calculated using the stoichiometry of the balanced redox equation. The balanced equation for the reaction involving ascorbic acid (C₆H₈O₆) and citric acid (C₆H₈O₇) can be represented as:
C₆H₈O₆ + C₆H₈O₇ → products
From the given information that 2.354×10⁻⁵ moles of ascorbic acid (C₆H₈O₆) are in the sample, we can use the stoichiometric coefficients from the balanced equation to find the moles of citric acid (C₆H₈O₇) in the sample.
Since the balanced equation indicates a 1:1 mole ratio between ascorbic acid and citric acid, the number of moles of citric acid is also 2.354 × 10⁻⁵ moles.
Therefore, the correct action in this context is to calculate the moles of citric acid in the sample.
This process involves applying the principles of stoichiometry, ensuring that the reaction equation is balanced, and using the mole ratios to relate the quantities of substances involved in the reaction.(option b)
