Lead acetate is one ionic compound with the formula , in which command is current in +2 oxidation state. That is a white crystalline solid. It has a slight sweet taste. It is additionally known together Plumbous acetate, salt the Saturn, sugar of lead, Goulard’s flour or lead diacetate. Its organized IUPAC surname is Lead(II) ethanoate. Command acetate is additionally toxic like other lead compounds. Yet it still has actually various applications such together a fixative and additionally as a reagent because that synthesis of other compounds. The was also used as a sweetener however soon it to be banned because of its toxic nature. That was uncovered in the united state in 1944.

Structure of lead Acetate

It is an ionic compound which is formed by the reaction of element lead and also acetic acid. It has actually one Pb2+ ion and two CH3COO- ions. As lead cation consists of +2 charge while every acetate anion has actually -1 charge, therefore the compound lead(II) acetate contains zero charge.

Properties of lead Acetate

Physical and also chemical nature of lead acetate - nature of command acetate are provided below –

Molar fixed of anhydrous command acetate is 325.29 g.mol-1.

Molar mass of its trihydrate (Pb(CH3COO)2.3H2O) kind is 379.33 g.mol-1.

It is a white fancy efflorescent crystalline solid.

It is slightly sweet in taste.

It has a satisfied acetic smell.

Its thickness in that is anhydrous kind is 3.25 g.cm-3 while in the trihydrate kind is 2.55 g.cm-3.

Melting point of anhydrous command acetate is 280 °C. If melting point of trihydrate lead acetate is 75 °C.

Anhydrous command acetate is dissolve in water and its solubility rises as temperature increases. For example, 19.8 gram of it is dissolve in 100ml water in ~ 0 °C while 44.3 grams are soluble in 100ml water at 20 °C.

It is additionally soluble in alcohol, glycerol etc.

It is very soluble in methanol. Because that example, in ~ 66.1 °C temperature, 102.75 grams of command acetate is dissolve in 100 grams that methanol.

Its 20 grams space soluble in 100 g the glycerol at 15 °C.

It has actually monoclinic crystal structure.

It is a non – flammable yet toxic compound. On oral consumption, 400mg/kg of it deserve to be lethal for mice.

It is basic in nature.

Its conventional enthalpy of formation is -960.9 kJ.mol-1.

Reaction v hydrogen sulfide – that reacts v hydrogen sulfide and forms lead sulfide and acetic acid. Reaction is given below –

Pb(C2H3O2)2 + H2S → PbS + 2CH3COOH

Reaction through potassium chromate – it reacts v potassium chromate and also forms command chromate and also potassium acetate. Reaction is given listed below –

K2CrO4 + Pb(C2H3O2)2 → PbCrO4 + 2CH3COOK

Production of command Acetate

It deserve to be created by adhering to two methods –

By reaction of acetic acid, hydrogen peroxide and also elemental lead

By reaction the copper acetate and lead metal

By reaction the acetic acid, hydrogen peroxide and also elemental lead – Elemental lead is boiled in acetic acid and hydrogen peroxide which result into command acetate and also water. Lead carbonate or lead oxide deserve to be offered in place of elemental lead. Reaction is given below –

Pb(s) + H2O2(aq) + 2H+(aq) → Pb2+(aq) + 2H2O(l)

Pb2+(aq) + 2CH3COO−(aq) → Pb(CH3COO)2(aq)

By reaction that copper acetate and lead metal – Lead metal on reaction v copper acetate displaces copper metal and forms command acetate by solitary displacement reaction. The equation is given listed below –

Cu(CH3COO)2 + Pb → Cu + Pb(CH3COO)2

Uses of command Acetate

Lead acetate was provided as a sweetener due to its slight sweet taste. Ancient Romans offered to cook grape juice in lead pots to create reduced street syrup. This street syrup was dubbed defrutum. Yet after a few years that was recognized that lead compounds (or command acetate) are toxic and were resulting in lead poisoning in those who were consuming the sugar syrup. Currently, its usage as a sweetener is banned.

Lead acetate has been widely supplied in the cosmetic industry for a lengthy time but due to its toxicity, presently the use has actually been limited. Nowadays it is greatly used in manufacturing of hair color products. Although in many places such together Canada, european Union and California command acetate is fully banned in food items and also cosmetic products as well due that is carcinogenicity and also reproductive toxicity. The was likewise used together a remedy because that sore nipples.

Lead acetate solution which is additionally known together Goulard’s Extract is provided as an astringent to constrict mucous membrane and also exposed tissues in contemporary medicine. Specifics Goulard’s extract is a equipment of lead acetate and lead oxide which was first introduced through French surgeon thomas Goulard.

A paper made increase of lead acetate is offered in detection the poisonous gas H2S. Moist command acetate top top reaction through hydrogen sulfide gas provides lead sulfide.

It is also used in cleaning and also maintenance that stainless steel suppressors and compensators. That was additionally used in making matchsticks throughout the medieval period. Street of command is used in boiled linseed oil to increase its effectiveness.
