Lead(II) sulfate

Lead(II) sulfate is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lead(II) sulfate rather than just read about it. In short: Lead(II) sulfate (PbSO4) is a white solid, which appears white in microcrystalline form. It is also known as fast white, milk white, sulfuric acid lead salt or anglesite.

Key takeaways

Lead(II) sulfate belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Lead(II) sulfate to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lead(II) sulfate from memory before moving on to harder problems.

Reference excerpt

Lead(II) sulfate (PbSO4) is a white solid, which appears white in microcrystalline form. It is also known as fast white, milk white, sulfuric acid lead salt or anglesite. It is often seen in the plates/electrodes of car batteries, as it is formed when the battery is discharged (when the battery is recharged, then the lead sulfate is transformed back to metallic lead and sulfuric acid on the negative terminal or lead dioxide and sulfuric acid on the positive terminal). Lead sulfate is poorly soluble in water.

Structure Anglesite (lead(II) sulfate, PbSO4) adopts the same orthorhombic crystal structure as celestite (strontium sulfate, SrSO4) and barite (barium sulfate, BaSO4). All three minerals' structures are in the space group Pbnm (number 62). Each lead(II) ion is surrounded by 12 oxygen atoms from 7 sulfate ions, forming a PbO12 polyhedron. The lead–oxygen distances range from 2.612 Å to 3.267 Å and the average distance is 2.865 Å.

Manufacturing Lead(II) sulfate is prepared by treating lead oxide, hydroxide or carbonate with warm sulfuric acid or by treating a soluble lead salt with sulfuric acid. Alternatively, it can be made by the interaction of solutions of lead nitrate and sodium sulfate.

Toxicology Lead sulfate is toxic by inhalation, ingestion and skin contact. It is a cumulative poison, and repeated exposure may lead to anemia, kidney damage, eyesight damage or damage to the central nervous system (especially in children). It is also corrosive - contact with the eyes can lead to severe irritation or burns. Typical threshold limit value is 0.15 mg/m3.

Mineral The naturally occurring mineral anglesite, PbSO4, occurs as an oxidation product of primary lead sulfide ore,

Basic and hydrogen lead sulfates A number of lead basic sulfates are known: PbSO4·PbO; PbSO4·2PbO; PbSO4·3PbO; PbSO4·4PbO. They are used in manufacturing of active paste for lead–acid batteries. A related mineral is leadhillite, 2PbCO3·PbSO4·Pb(OH)2. At high concentration of sulfuric acid (>80%), lead hydrogensulfate, Pb(HSO4)2, forms.

Chemical properties Lead(II) sulfate can be dissolved in concentrated HNO3, HCl, H2SO4 producing acidic salts or complex compounds, and in concentrated alkali giving soluble tetrahydroxidoplumbate(II) [Pb(OH)4]2− complexes.

PbSO4(s) + H2SO4(l) ⇌ Pb(HSO4)2(aq) PbSO4(s) + 4 NaOH(aq) → Na2[Pb(OH)4](aq) + Na2SO4(aq) Lead(II) sulfate decomposes when heated above 1000 °C:

PbSO4(s) → PbO(s) + SO3(g)

Worked examples

Example 1 — a first encounter with Lead(II) sulfate

Start with the simplest possible case. Write down what Lead(II) sulfate claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lead(II) sulfate before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lead(II) sulfate ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lead(II) sulfate

In research: Lead(II) sulfate appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lead(II) sulfate in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lead(II) sulfate is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lead(II) compounds, Sulfates, so understanding it makes those chapters shorter.
In everyday life: Look for Lead(II) sulfate outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
