• lead(II) nitrate – Pb(NO3)3
▪ lead (III) → +3 charge → Pb3+
▪ nitrate → polyatomic ion → -1 charge → NO3-
• Sodium hydroxide – NaOH
▪ sodium → group 1A → +1 charge → Na+
▪ hydroxide → polyatomic ion → -1 charge → OH-
Write the balanced chemical equation for each of these reactions. Include phases.
1. When aqueous sodium hydroxide is added to a solution containing lead(II) nitrate, a solid precipitate forms.
2. However, when additional aqueous hydroxide is added the precipitate redissolves forming a soluble [Pb(OH)4]2-
