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.
Why do you use kcl for making salt bridge?
A salt bridge is used in electrochemical cells to allow for the flow of ions between the half-cells. Potassium chloride (KCl) is a commonly used salt for making salt bridges because it provides a source of mobile ions (K+ and Cl-) that can help maintain electrical neutrality in the half-cells by allowing the flow of ions to balance the charge buildup.
What is the accepted Ka value for sodium hydroxide?
The accepted Ka value for sodium hydroxide (NaOH) is not applicable, as NaOH is a strong base and completely dissociates in water. Instead, the equilibrium constant Kb (base dissociation constant) is typically used for strong bases. The Kb value for NaOH is approximately 1 x 10^-15.
What does the reaction of hydrogen chloride and sodium hydroxide produce?
hydrochloric acid + sodium hydroxide --> sodium chloride + waterHCl + NaOH --> NaCl + H2ONeutralisationAcids and alkalis react with each other. The alkali cancels out the acid in the reaction. This is called neutralisation. A salt is made. The salt contains the metal atom from the alkali, and part of the acid molecule. The salt made depends on the acid and alkali used.
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.
What happens when an ester is reacted with NaOH?
When an ester is reacted with NaOH, it undergoes hydrolysis to form the corresponding carboxylate salt and alcohol. The reaction is typically called saponification and is often used in the production of soap.
What would happen to the cell potential if a salt bridge is not used?
If a salt bridge is not used, the cell potential would decrease because without a salt bridge, the flow of ions between the two half-cells would be disrupted, leading to a buildup of charge and a decrease in the efficiency of the cell.

How much of NaOH were used in the titration?
The amount of NaOH used in a titration depends on the volume and concentration of the NaOH solution used in the experiment. To calculate the exact amount of NaOH used, you would need to know the molarity of the NaOH solution and the volume used in the titration.
What are the uses of calomel electrodes?
The calomel electrodes are usually used as the salt bridge.
What kind of electrolyte used in salt bridge and why?
Kcl because of its high conductivity
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.
Is salt and water an appropriate substitute for sodium hydroxide?
Unlikly; as the NaOH solution is quite caustic. In fact its "generic" name is "Draino" or "Lye". It is also used to change animal fat to soap. You may swim in salt water; however, you may "turn to soap", if you swim in NaOH :-)!
NaOH is an example of?
NaOH is an example of a strong base, commonly known as sodium hydroxide. It is a highly caustic substance and is used in various applications such as cleaning agents, soap production, and as a chemical reagent in laboratories.
NaCl and NaOH are chemical symbols or formulas?
NaCl is the chemical formula for sodium chloride, also known as table salt. NaOH is the chemical formula for sodium hydroxide, which is a strong base commonly used in cleaning products.
Could a voltmeter be used in a wheatstone bridge instead of an ammeter?
Yes, of course.
