Benzoic acid (an organic acid) is soluble in which of the following organic solvents? Diethyl ether Water Sodium hydroxide ( \( \mathrm{NaOH} \) 6M) All of the above! Suppose, the weight of the unknown mixture you started with is \( 142.3 \mathrm{mg} \). The weight of the extracted benzoic acid is \( 41.7 \mathrm{mg} \). The weight of the extracted naphthalene is \( 48.8 \mathrm{mg} \). You can combine the weights of the chemicals you isolated and compare that weight to the weight you started with to determine a percent recovery. Calculate the extraction recovery efficiency (i.e. percent recovery). Equation: \( \% \) recovery \( = \) (combined weight of the isolated compounds/weight of the starting mixture) \( \times 100 \) \begin{tabular}{l} \( 93.5 \% \) \\ \( 83.5 \% \) \\ \( 73.5 \% \) \\ \hline \( 63.5 \% \) \end{tabular} Your recovery is highly unlikely to be exactly \( 100 \% \). Which of the following are possible reasons why your recovery is less than \( 100 \% \) ? Mechanical losses (e.g. during transfers) Incomplete deprotonation Incomplete reprotonation All of the above are possible reasons!
