Detailed explanation-1: -When a sodium chloride is added to a solution containing lead (II) nitrate, a white precipitate of (fairly) insoluble lead chloride will result.
Detailed explanation-2: -Double displacement NaCl + Pb(NO3)2 | Sodium chloride + Lead(ii) nitrate | Precipitation reaction.
Detailed explanation-3: -Lead(II) Nitrate with Sodium Hydroxide Here, sodium hydroxide (NaOH) is added to lead(II) nitrate (Pb(NO3)2). The result is a white precipitate.
Detailed explanation-4: -The lead nitrate [Pb(NO3)2] reacts with potassium iodide (Kl) causing exchange of ions between the reactants leading to the formation of potassium nitrate (KNO3) and a yellow precipitate of lead iodide (PbI2). The reaction involved is given below: Pb(NO3)2(aq)+2KI (aq)→PbI2(s)(↓)+2KNO3(aq)
Detailed explanation-5: -Answer and Explanation: When colorless lead nitrate is reacted with colorless sodium sulfide, it will form a dark brown precipitate of lead sulfide. Therefore, the formula of precipitate is PbS P b S .
