Write the balanced chemical equation for each of these reactions. Include phases.

When aqueous sodium hydroxide is added to a solution containing lead(II) nitrate, a solid precipitate forms.

However, when additional aqueous hydroxide is added the precipitate redissolves forming a soluble [Pb(OH)4]2–(aq) complex ion.

You have an aqueous solution of chromium(III) nitrate that you titrate with an aqueous solution of sodium hydroxide. After a certain amount of titrant has been added, you observe a precipitate forming. You add more sodium hydroxide solution and the precipitate dissolves, leaving a solution again. What has happened?

You have an aqueous solution of chromium(III) nitrate that you titrate with an aqueous solution of sodium hydroxide. After a certain amount of titrant has been added, you observe a precipitate forming. You add more sodium hydroxide solution and the precipitate dissolves, leaving a solution again. What has happened?

The precipitate was chromium hydroxide, which dissolved once more solution was added, forming Cr3+(aq).
The precipitate was sodium nitrate, which reacted with more nitrate to produce the soluble complex ion Na(NO3)2−.
The precipitate was sodium hydroxide, which re-dissolved in the larger volume.
The precipitate was chromium hydroxide, which then reacted with more hydroxide to produce a soluble complex ion, Cr(OH)4−.
