Mix it slowly in a glass, HDPE, or stainless container and use all safety equipment (gloves, eyewear, and ventilation). Always add powder to the liquid and if it gets hot to the touch, slow down.
Both chemicals absorb water from the atmosphere, so choose your location and the day appropriately.
Elemental sodium and pure methanol will react to produce sodium methoxide and hydrogen gas.
2Na + 2CH3OH --> 2CH3ONa + H2
Slowly dissolving the necessary quantity of NaOH in the necessary volume of methanol.
Add sodium metal to methanol
how will you prepare 0.38M sodium acetate solution
The methoxide ion would steal a hydrogen ion from water, forming sodium hydroxide and methanol. CH3ONa + H2O --> CH3OH + NaOH
Firstly, sodium methoxide is extremely toxic, so you want to handle it carefully without ever spilling (e.g. from an unsealed container). Secondly, methanol is hygroscopic and will pick up lots of water from the atmosphere. Water will hydrolyze sodium methoxide into methanol and sodium hydroxide. You wouldn't want your methanol to evaporate either.
No. Alkoxide ions are stronger bases than hydroxide ions. The only way of making an alkoxide is by reacting a hihgly reactive metal such as sodium with the corresponding alcohol (react sodium with methanol to produce sodium methoxide). In water sodium methoxide will react to produce sodium hydroxide and methanol.
Cl-CH3_CH2_CH2_CH3+C2H5oNa_> C6H15o+
Preperation ofIsoxazole Ester by using sodium methoxide, diethyl oxalate and ...
sodium azide + methanol
NaOH + CH3OH --> CH3ONa + H2O Evaporate the solution to dryness, add more CH3OH and evaporate to dryness. you can repeat a few times to ensure the remaining solid is sodium methoxide
The sodium methoxide reacts with the water to produce sodium hydroxide an methanol.
how will you prepare 0.38M sodium acetate solution
A sodium solution of water cannot be made as sodium reacts violently with water to produce sodium hydroxide.
The methoxide ion would steal a hydrogen ion from water, forming sodium hydroxide and methanol. CH3ONa + H2O --> CH3OH + NaOH
Sodium chloride is used to prepare the 0,9 % isotonic solution.
Firstly, sodium methoxide is extremely toxic, so you want to handle it carefully without ever spilling (e.g. from an unsealed container). Secondly, methanol is hygroscopic and will pick up lots of water from the atmosphere. Water will hydrolyze sodium methoxide into methanol and sodium hydroxide. You wouldn't want your methanol to evaporate either.
To prepare a buffer solution which may be acidic. Titrate ethanoic acid (weak acid) with sodium ethanoate(salt).
Potassium Hydroxide is stronger than sodium hydroxide
No. Alkoxide ions are stronger bases than hydroxide ions. The only way of making an alkoxide is by reacting a hihgly reactive metal such as sodium with the corresponding alcohol (react sodium with methanol to produce sodium methoxide). In water sodium methoxide will react to produce sodium hydroxide and methanol.
