a 5.40 g sample of sodiem hydrogen carbonate reacts with excess acetic acid to form sodium acetate by the reaction below. when the reaction is comple 4.80 g of sodium acetate recovered

Answer 1

Write a balanced equation for the reaction:

NaHCO3 + CH3COOH ==> CH3COONa + H2CO3 ==> CO2 + H2O + CH3COONa

Theoretical yield of CH3COONa:

5.40 g NaHCO3 x 1 mol NaHCO3/84.0 g x 1 mol CH3COONa/mol NaHCO3 x 82.0 g/mol = 5.27 g

Percent yield:

actual yield/theoretical yield (x100%) = 4.80 g/5.27 g (x100%) = 91.1% yield
