Sodium acetate on heating with NaOH and CaO (3:1 mixture) gives _______

Sodium acetate on heating with NaOH and CaO (3:1 mixture) gives _______ Correct Answer methane

Sodium acetate undergoes decarboxylation (loss of CO2) when heated with soda lime. This is proceeded by the loss of COONa from the sodium salt and NaO from sodium hydroxide. They combine to form CH4 and Na2CO3. The hydrocarbon formed has one less carbon atom than the parent acid.

Measurement of KLa in a bioreactor can be carried out by sodium sulfite oxidation method, that is, based on the oxidation of sodium sulfite to sodium sulfate in the presence of a catalyst (Cu++ or Co++). In a typical experiment, a laboratory fermenter was filled with 5 liter of 0.5 M sodium sulfite solution containing 0.003 M Cu++ ions and the air was sparged in. After 10 min, the air flow was stopped and a 10 mL sample was taken and titrated. The concentration of sodium sulfite in the sample was found to be 0.20 M. The oxygen uptake rate for this aerated system will work out to be
