How many moles of NaOH were used in the titration process?
The number of moles of NaOH used in the titration process can be calculated by dividing the volume of NaOH solution used by the molarity of the NaOH solution.
Why do you use ethanolic NaOH instead of aq NaOH in titration?
Ethanolic NaOH is used instead of aqueous NaOH in titration to avoid side reactions with water and reduce error in the titration process. The absence of water in ethanolic NaOH helps maintain the concentration and stability of the solution, resulting in more accurate and precise titration results.
How can one standardize NaOH?
To standardize NaOH, one must titrate it against a known concentration of an acid, such as HCl, using an indicator to determine the endpoint of the reaction. The volume and concentration of the NaOH can then be calculated based on the volume of acid used in the titration. This process ensures that the concentration of the NaOH solution is accurately determined for future use in experiments.
Which is better process to prepare NaOH nelson cell or castner-kellner?
Caster kellner's cell method is better because, 1- it gives about 100% pure NaOH. 2-a large quantity of NaOH can be prepared in a short time. 3- NaOH and Cl2 are formed in separate chamber and can not react with each other.
Why do we standardize the NaOH solution that we made by dissolving a measured mass of solid NaOH?
Standardizing the NaOH solution by dissolving a measured mass of solid NaOH ensures that the concentration of the solution is accurately known and consistent for use in experiments or analyses.
What are the functions of NaOH in benzoylation of amine?
Sodium hydroxide (NaOH) is used as a base in benzoylation reactions of amines to deprotonate the amine, forming the corresponding amine salt. This salt formation helps to make the amine more reactive towards the benzoyl chloride reagent, facilitating the acylation step. NaOH also helps to maintain the reaction environment at a basic pH, which is ideal for the reaction to proceed efficiently.
What is benzoylation definition?
Benzoylation is a type of substitution reaction in which the hydrogen of amide group or hydroxy group of aromatic benzene group take place.

How much NaOH do you use to lower pH?
You dont - adding NaOH increases pH.
How many liters of naoh are in 1.3 moles of 3.42 m of naoh?
Molarity = moles of solute/Liters of solution 3.42 M NaOH = 1.3 moles NaOH/Liters NaOH Liters NaOH = 1.3 moles NaOH/3.42 M NaOH = 0.38 Liters
What happens when fatty acid reacts with NaOH?
what happen when fatti acid react with the NaOH
Why do we standardize the NaOH solution that we made by dissolving a measured mass of solid NaOH?
Standardizing the NaOH solution by dissolving a measured mass of solid NaOH ensures that the concentration of the solution is accurately known and consistent for use in experiments or analyses.
What volume of NaOH was used in the titration?
To determine the volume of NaOH used in the titration, you need to know the concentration of the NaOH solution and the volume required to reach the endpoint. Use the formula: volume NaOH (L) = volume HCl (L) * concentration HCl / concentration NaOH.
What is the concentratuon of a hcl solution if 25.0 ml is required to neutralize 38.5 ml of a 0.500m solution of naoh?
To find the concentration of HCl, you can use the formula: moles of NaOH = moles of HCl. From the given information, you can calculate the moles of NaOH used to neutralize the acid. Then, use the volume and concentration of NaOH to determine the concentration of HCl.
