Calculate the theoretical yield of 2mL of vegetable oil saponification reaction with 2mL of 6M NaOH and 40mL of saturated salt solution(NaCl). GIVENS: density of the oil = 0.9 g/mL each fatty acid side chain of the oil has 18 C atoms (C_18: the carbonyl carbon, plus a C_17 carbon chain). Assume an average of one unsaturation per side chain.
Calculate the theoretical yield of 2mL of vegetable oil saponification reaction with 2mL of 6M NaOH and 40mL of saturated salt solution(NaCl).
GIVENS:
density of the oil = 0.9 g/mL
each fatty acid side chain of the oil has 18 C atoms (C_18: the carbonyl carbon, plus a C_17 carbon chain). Assume an average of one unsaturation per side chain.
Explanation
The theoretical yield of a saponification reaction can be calculated by considering the amount of fatty acids present in the vegetable oil, and the stoichiometry of the reaction with sodium hydroxide.
In a saponification reaction, one mole of sodium hydroxide reacts with one mole of fatty acid to form sodium salt of fatty acid and water:
C17H33COOH + NaOH → C17H33COONa+ H2O
Hence theoretical yield can be calculated according and given in next section.
