Why phenoxide ion is more reactive than phenol toward electrophilic subsititution reaction?
In the phenoxide ion the charge is delocalized by the resonance in the benzene ring. There is no such delocalization in the ethoxide ion.
Why phenol is more stable in sodium hydroxide than in water?
Because in sodium hydroxide it forms phenoxide ion which is stabilized by solvolysis.
Which ion is responsible for the colour that has observed in the copper2 solution?
sulphate
Is sodium chloride a reactant or product?
It can be either, depending on the reaction. Sodium chloride is a product of the reaction of sodium hydroxide and hydrochloric acid. Sodium chloride is a reactant in the ion exchange reaction in a water softener to remove calcium from hard water.
Which ion is responsible for the colour that is observed in the CuCl2 solution?
CuCl2(s) = Cu^2_(aq) + + 2Cl^-(aq) In solution the chloride anions )Cl^-) are colourless ; see also dissolved common salt (NaCl) So it must be the copper cations (Cu^2+) that gives the colour blue.

What ion is produced when phenol acts as an acid?
The ion produced is phenoxide ion.
What is phenoxide?
Phenoxide ion is C6H5O-, formed when phenol, C6H5OH is treated with a base like NaOH.
Which one is more soluble in water phenol or sodium phenoxide ion?
Carboxylic acid.
Why phenol is more stable in sodium hydroxide than in water?
Because in sodium hydroxide it forms phenoxide ion which is stabilized by solvolysis.
What colour is sodium ion?
Sodium ion is colorless.
Is there any noticeable correlation between the metal ion radius and the colour or lack of colour of the ion in solution?
no
Why are phenols acidic in nature?
Phenol can act as an acid due to it's stability as phenoxide ion. By releasing H+ ion it will form stable C6H5O- ion. The groups having +I, -I , +M , -M efffects present on phenol will effect acidic nature of phenol. As +I or +M groups which are present at ortho and at para psitions will decrease the acidic character of phenol. If they are at meta position effect is less than at para or ortho positions.Similar to this -I or -M gorups are substituted on phenol they will increase the acidic nature. so, we can say that as the stability of phenoxide ion increases acidic nature of phenol also increases.Phenol can act as an acid due to it's stability as phenoxide ion.

What colour is the sulfite ion?
Colourless mate
Is sodium phenoxide soluble?
yes
What happens in the reaction of sodium phenoxide with sulforic acid?
When the reaction of sodium phenoxide and sulforic acid occurs, the esters are usually produced.
Why phenol do not give protonation reaction readly?
Electron density on oxygen in phenoxide ion is decreased due to resonance. The oxygen rather acquire a positive charge. Therefore phenol does not give protonation readily
