Dear chemists, I really need your help..?

Question

If a grain of table salt will be placed in 5mL of 0.1M silver nitrate, what will be its result? what type of change will take place?

If 0.5g of table salt will be placed in 5mL of water in a test tube, will there be any change in taste and color? If this solution will be placed in an evaporating dish and evaporate to dryness over a flame, how would the residue differ with the original table salt as to color, and reaction with silver nitrate.

What type of change takes place when table salt dissolves in water?

Please I really need your help..
Thank you.

Answer 1

1. The grain of salt just dissolves, no specific change at all.
2. Taste becomes salty ,no colour change.
Salt obtained(residue) will have the same properties as that of normal salt.

Reaction:

AgNO3 + NaCl -------------- AgCl + NaNO3

3. Salt on dissolving in water dissociates in to Na+ cation and Cl- anions.
These ions are solvated by water molecules

Answer 2

If a grain of table salt i.e. NaCl is added to silver nitrate it will result in formation of silver chloride that forms white precipitate.
When salt is added to water it will change the taste, it will become salty but on change in colour. When you evaporate this salt will reappear, no change in colour and it's reaction with silver nitrate.
When it dissolves it is just a physical change.

Answer 3

. The grain of salt just dissolves. no change at all.
2.Taste becomes salty ,no colour change.
