Why is it water requires to be boiled first before add to NaOH?
The water as it was was impure, that is, it contained other impurities such as sulphur and other element. Boiling the water will remove the impurities so that when the water is added to the NaOH, any reaction will be between the water and NaOH only. If the water was not boiled, the impurities in the water could react with the water.

What is the chemical reaction that causes an egg to become hard-boiled?
The chemical reaction is caused by the conflict of the sulphur from the yolk and the chemicals in the albumen in the white. This is why hard-boiled eggs get that very unappetizing green ring between the white and yolk.
Why is a dark ring sometimes seen around the yolk of a boiled egg?
Most people over cook their hard boiled eggs. Hydrogen sulphide generated by the decomposition of sulphur-containing amino acids in the white will react with iron in the yolk causing a (harmless) grey-green film of ferrous sulphide to form on the surface of the yolk. Put 2 week old eggs (fresh eggs are hard to peel, and by the time eggs reach the store they are about a week old) in saucepan covered by a inch of water. Bring to a rolling boil on high. Immediatly reduce heat to medium and leave for 10 minutes. Put eggs into ice water for a few minutes. Peel.
When a piece of hard boiled egg is left in contact with silver spoon a black spot is formed on the spoon explain?
They only get the black ring if you do not refresh after cooking, as soon as the eggs are boiled pour off the hot water and put the eggs under a cold running tap for a few minutes, this quickly cools the eggs and prevents the black ring.

What is a boiled egg?
An egg that has been boiled in hot water for a bit, put in the fridge, and then the shell is peeled off, and the white and yolk would be solid, and ready to eat!A boiled egg can be best defined as a mass of denatured protein, that became denatured by its subjection to heat. Unfortunatly for the egg this process is irreversible. Other ways that proteins can be denatured include changes to the pH of their environment, since this disrupts hydrogen, di-sulphide and peptide bonding in regions of the protein responsible for the stabilization of its secondary and primary structure.
