2) Take careful consideration in pretty small precipitates.

Answer 2

Answer:

• The anion is the one which has gained an electron and it becomes negatively charged.
• The cations are the one which has gained negative charge. The cationic reagent are used for the identification of anionic solution.
• The reagents are the one which is used for the separation of ions. These are the common cations silver (Ag), lead (Pb) etc.
• The reagents which is used are silver nitrate, hydro chloric acid, sodium hydroxide are the most common cationic reagent used.
