Nitrate of lead. It is obtained by dissolving lead oxide (II) PbO, lead white Pb(OH) 2.2PbCO3 or metallic lead in nitric acid. It is a colorless crystal. It decomposes to lead oxide (II) and nitrogen dioxide at temperatures above 470°C. It is hardly soluble in concentrated nitric acid. It is soluble in water. Lead hydroxide (II) is precipitated by alkali hydroxide, but if it dissolves in excess it becomes zincate. It is used as a raw material for making pigments, matches, explosives, preservatives, astringents, dyes, and reagents.

鉛の硝酸塩。酸化鉛(Ⅱ)PbOや鉛白Pb(OH)2・2PbCO3または金属鉛を硝酸に溶かして得られる。無色の結晶。470℃以上で酸化鉛(Ⅱ)と二酸化窒素とに分解する。濃硝酸には溶けにくい。水に溶ける。水酸化アルカリにより水酸化鉛(Ⅱ)を沈殿するが、過剰に溶けて亜鉛(あなまり)酸塩となる。顔料の製造原料、マッチ、爆薬、防腐剤、収斂(しゅうれん)剤、染色、試薬などの用途がある。 [守永健一・中原勝儼] [参照項目] | [補完資料] |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
