Reactions
Apart from lead(II) acetate, lead(II) nitrate is the only common soluble lead compound. Lead(II) nitrate readily dissolves in water to give a clear, colourless solution. As an ionic substance, the dissolution of lead(II) nitrate involves dissociation into its constituent ions.
- Pb(NO3)2 (s) → Pb2+ (aq) + 2 NO−
3 (aq)
Lead(II) nitrate forms a slightly acidic solution, with a pH of 3.0 to 4.0 for a 20% aqueous solution.
When concentrated sodium hydroxide solution is added to lead(II) nitrate solution, basic nitrates are formed, even well past the equivalence point. Up through the half equivalence point, Pb(NO3)2·Pb(OH)2 predominates, then after this point Pb(NO3)2·5Pb(OH)2 is formed. No simple Pb(OH)2 is formed up to at least pH 12.

Famous quotes containing the word reactions:
“We have all had the experience of finding that our reactions and perhaps even our deeds have denied beliefs we thought were ours.”
—James Baldwin (1924–1987)
“Cuteness in children is totally an adult perspective. The children themselves are unaware that the quality exists, let alone its desirability, until the reactions of grownups inform them.”
—Leontine Young (20th century)
“In this Journal, my pen is a delicate needle point, tracing out a graph of temperament so as to show its daily fluctuations: grave and gay, up and down, lamentation and revelry, self-love and self-disgust. You get here all my thoughts and opinions, always irresponsible and often contradictory or mutually exclusive, all my moods and vapours, all the varying reactions to environment of this jelly which is I.”
—W.N.P. Barbellion (1889–1919)
