By karl-fischer titration meant for moisture content.
Step 1: Weigh about 13.0g of salicylic acid and transfer into 100ml of volumetric flask, add 30ml of methanol sonicate to dissolve and make upto the mark with methanol
Step 2: Calculate the water equivalent factor
Step 3: Take 30ml of methanol, neutralize it and add 10ml of salicylic acid solution continue the titration. Note down the end point (Y)
Step 4: Add accuratelu 0.5g of sample and 10ml of salicylic acid titrate with Kf reagent and note down the end point (X)
Step 5: Calculation (x-y) and the factor is 2.222

Which is the stronger base what Sodium Hydroxide or Potassium Hydroxide?
Potassium Hydroxide is stronger than sodium hydroxide
Examples of acid and bases?
Acids: hydrochloric acid, sulphuric acid, nitric acid Bases: sodium hydroxide, potassium hydroxide, sodium methoxide
How do you get sodium methoxide from sodium hydroxide and 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
Is sodium methoxide solution soluble in toluene?
Preperation ofIsoxazole Ester by using sodium methoxide, diethyl oxalate and ...
What is the Name for NaOH?
The chemical name is Sodium Hydroxide. It is made of Na+ ions and OH- ions.
Which is the stronger base what Sodium Hydroxide or Potassium Hydroxide?
Potassium Hydroxide is stronger than sodium hydroxide
What happens if sodium methoxide 25 percent in methanol reacts with water?
The sodium methoxide reacts with the water to produce sodium hydroxide an methanol.
Would the alkoxide form if an hydroxide was dissolved in methanol?
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.
Examples of acid and bases?
Acids: hydrochloric acid, sulphuric acid, nitric acid Bases: sodium hydroxide, potassium hydroxide, sodium methoxide
What would you expect to happen if sodium methoxide were added to water?
The methoxide ion would steal a hydrogen ion from water, forming sodium hydroxide and methanol. CH3ONa + H2O --> CH3OH + NaOH
How do you get sodium methoxide from sodium hydroxide and 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
Why should sodium methoxide 25 percent in methanol be kept tightly closed when not in use?
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.

What is the reaction between Hydrazoic acid and Sodium methoxide solution?
sodium azide + methanol
What is the Name for NaOH?
The chemical name is Sodium Hydroxide. It is made of Na+ ions and OH- ions.
NaOH base or acid?
Sodium hydroxide is basic.
Is gel make when magnesium methoxide reaction with methanol?
No. Magnesium methoxide will react with water to form a gel. The gel is actually a cross-linked Magnesium hydroxide structure in methanol. Magnesium methoxide is typically sold/stored in dry methanol to protect the chemical as it is incredibly hygroscopic.
