Why is NaOH heated before adding BaCl2?
Heating NaOH before adding BaCl2 helps to dissolve NaOH completely in water, ensuring that no solid NaOH remains undissolved in the solution. This is important because the reaction between BaCl2 and NaOH requires the NaOH to be in solution to react with the BaCl2. Heating the solution can also speed up the reaction between NaOH and BaCl2.
What happens when phenol is warmed with CCl4 in aqueous NaOH?
In the presence of aqueous NaOH, phenol undergoes nucleophilic aromatic substitution reaction to form sodium phenoxide. When CCl4 is added, no reaction occurs as CCl4 is non-reactive towards phenoxide ion.
What happens if pepsin is added to NaOH?
If pepsin, an enzyme that breaks down proteins, is added to sodium hydroxide (NaOH), a strong base, the high pH of the NaOH will denature and inactivate the pepsin enzyme. Denaturation is the process where the protein loses its shape and function due to changes in pH, temperature, or other conditions. This would prevent pepsin from being able to digest proteins in the presence of NaOH.
What will be the product of the reaction of ethanol and NaOH and iodine?
The reaction of ethanol with NaOH and iodine will yield iodoethane (ethyl iodide) as the product. The alcohol group in ethanol will be replaced by the iodine atom in the presence of NaOH.
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 happens to sodium hydroxide when heated?
At very high temperature NaOH is decomposed and Na2O fumes are emited.The reaction is:2 NaOH = Na2O = H2O
What happens when all metal dissolve in alkalis like sodium hydroxide?
Some metals react with alkalis; for example the reaction of aluminium with sodium hydroxide is:2 Al + 2 NaOH + 2 H2O = 2 NaAlO2 + 3 H2
Why the NaOH solution is heated before adding BaCl2 in the two solutions method for determination of purity of NaOH sample?
Why the NaOH is heated before adding in BaCl2 for determination of purity of NaOH sample?
How many moles of H2 can you get from 4 moles of Al?
This reaction is:2 Al + 2 H2O + 2 NaOH = 2 NaAlO2 + 3 H2From 4 moles of Al 6 moles of hydrogen are obtained.
What happens if you swim in NaOH?
The alkali in NaOH would burn your skin.

What happens when you add NAOH to Hydrogen?
Nothing.

What happens when carbon dioxide is passed through NaOH solution?
2 NaOH(aq) + CO2(g) = Na2CO3(aq) + H2O(l)
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.
