Question

Which compound of lead is called sugar of lead?
(a) $PbC{{l}_{2}}$
(b) $Pb{{(N{{O}_{3}})}_{2}}$
(c) $PbS{{O}_{4}}$
(d) $Pb{{(C{{H}_{3}}COO)}_{2}}$

Answer 1

Hint: The physical property of the lead which has sweet taste , is used as the sugar, the lead and the oxidation state of the lead in that the very compound of lead is +2 and is formed when lead reacts with the acetic acid. Identify that compound.

Complete step by step answer:
Lead is a metal having the atomic number 82 and lies in the 14th group and belongs to the category of carbon family. It reacts with oxygen forming various oxides of lead i.e. The lead oxide PbO, lead dioxide $\text{Pb}{{\text{O}}_{\text{2}}}$, lead trioxide $\text{P}{{\text{b}}_{\text{2}}}{{\text{O}}_{\text{3}}}$ and triplumbic tetroxide $\text{P}{{\text{b}}_{\text{3}}}{{\text{O}}_{\text{4}}}$ $\text{P}{{\text{b}}_{\text{3}}}{{\text{O}}_{\text{4}}}$etc.
The compound of lead i.e. lead acetate having the molecular formula as $\text{Pb(C}{{\text{H}}_{\text{3}}}\text{COO}{{\text{)}}_{\text{2}}}$ , is commonly known as the sugar of the lead and its IUPAC name is lead ethanoate. It is formed lead oxide is made to react with the acetic acid and the resulting compound, so formed is called as the lead oxide.
Lead acetate is known from many names such as plumbous acetate, lead acetate, salt of Saturn, lead sugar or sugar of the lead etc. It is white crystalline in nature and because of its slightly sweet taste , it is commonly called as the lead sugar.

Hence, option (d) is correct.

Note: Lead acetate is commonly used in the laboratories as the laboratory reagent and a part from this , it is also used in the cosmetics, in gold mines, dyeing and also in the textile industries.
