What is the molarity of the aqueous NaOH?
This depends on the mass of NaOH dissolved in 1 L water.
Why it is necessary to cap the buret and minimize the CO 2 absorption from the NaOH solution. How will this affect your results?
When sodium hydroxide absorb carbon dioxide sodium carbonate is formed. But we need a defined mass (volume) of NaOH for a titration.
Discussion for acid-base titration experiment?
discussion for the titration of NaOH and HNO3 by using phenolphthalein & methyl orange indicators
What will happen to the molarity of NaOH If a drop of NaOH falls out of the flask during the titration?
You have to realise that a drop from the burette for instance is insignificant, if you are dealing with at least 10ml solution which you usually deal with on a titration. If you don't want to regard it as insignificant, then if NaOH is in the burette, then the solution doesn't become more concentrated with NaOH because that drop escaped.
How do you prepaire 0.05N NaOH from 1N NaOH?
Dissolve 20g of NaOH in about 500 mL of water and dilute with water to 1000mL. Mix well.
Why is it necessary to standardize the NaOH solution before titration?
It allows the concentration of the NaOH to be known.
Is coconut oil soluble in NaOH?
Nope. Coconut oil which is a lipid is insoluble in dilute alkali. Dilute NaOH is a dilute alkali.
Why you use oxalate potassium in formol titration?
In formol titration, amino acids with formaldehyde are titrated with NaOH to measure the amount of amino acids in the solution. Potassium is also necessary for this titration and is supplied by using potassium oxalate. If calcium is present, it will react with the NaOH to form Ca(OH)2. This will make it appear to need more of the NaOH solution (and overestimate the titration). Potassium oxalate will chelate the calcium, and prevent it from reacting (forming calcium oxalate).
What happened if some solution splashes out during the titration of NaOH?
If some solution splashes out during the titration of NaOH, the volume at the end point will be wrong.
HOW TO 0.1N NaOH solution preparation?
to prepare 1N we have to dilute 40gms of NaOH in 1 litre of water as for NaOH normality =molarity so to prepare 0.1N NaOH we have to dilute 4gms of NaOH in 1 litre of water..
What is hypothesis of a acid base titration?
to determine the concentration of the unknown solution and to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH.
Is coconut oil soluble in dilute NaOH?
No. Oils can be soluble in organic solvents such as chloroform or hexane.
What is the molarity of the aqueous NaOH?
This depends on the mass of NaOH dissolved in 1 L water.
Why it is necessary to cap the buret and minimize the CO 2 absorption from the NaOH solution. How will this affect your results?
When sodium hydroxide absorb carbon dioxide sodium carbonate is formed. But we need a defined mass (volume) of NaOH for a titration.
Standardisation of naoh solution in titration with citric acid?
the standard solution in the above titration is citric acid because out of citric acid and naoh only citric acid can be obtained in purest frem while naoh is hygroscopic in nature
Which indicator is used in titration of naoh and h2so4?
Methyl orange
What volume of NaOH was used in the titration?
Why all peoples are selfish
