How do you make 1M sodium methoxide?

Sodium Methoxide (0.1M)

Molecular formula: NaOCH3  

Molecular weight: 54.02 

Preparation: Cool 150 mL of anhydrous methanol in ice water and add a small portion of 2.5 g of freshly cut sodium. After the complete dissolution of the metal, add anhydrous toluene to produce 1000 mL. Store the solution in a container well protected from carbon dioxide and moisture.

Standardization: Weigh accurately about 0.4 g of benzoic acid, dissolve in 80 mL of dimethyl-formamide, add 0.1 mL thymol blue in dimethyl formamide as an indicator and titrate with sodium methoxide to give blue color as an endpoint. Perform a blank determination and make any necessary corrections. 


Sodium Methoxide (0.1M)

Factor Calculation: 

1 mole of NaOCH3 ≅ 1 mole of benzoic acid 

1000 mL of 1M NaOCH3 ≅ 122.12 g of C6H6COOH 

1 mL of 0.1M NaOCH3 ≅ 0.01221 g of C6H6COOH
