Does zinc contain lead?
No, zinc does not contain lead. Zinc and lead are two different elements with distinct chemical properties.
Why is zinc used in desilverisation of lead?
Zinc is used in the desilverization of lead because zinc has a higher affinity for silver than lead does. When zinc is added to molten lead containing silver, zinc combines with silver to form a zinc-silver alloy, which then floats to the surface for easy removal, leaving behind lead that is desilverized.
What is melting point of zinc and lead?
The melting point of zinc is 419.5°C, while the melting point of lead is 327.5°C.
Will a reaction take place if a strip of zinc metal is placed in a lead II sulfate solution?
Yes, a reaction will take place. The zinc metal will displace the lead in the lead(II) sulfate solution, forming zinc sulfate and lead metal. This is because zinc is higher in the reactivity series than lead.
How does the presence of zinc affect the extraction process of lead from its ore?
The presence of zinc can affect the extraction process of lead from its ore by forming a zinc-lead alloy, which has a lower melting point than pure lead. This allows for easier separation of lead from the ore during the smelting process.
Are diamonds heavier than lead?
No. The specific gravity of lead is 11.35 and the specific gravity of diamond is 3.5, which is above average, but not heavier than lead.

What is measured by Specific gravity of a lead acid cell?
Specific gravity of the electrolyte in the lead acid cell or battery (assuming that the battery is not of the sealed type) is often used as a measure of its STATE OF CHARGE. Sure we can do the same with a multimeter but the above method is more accurate.
Is soft lead copper aluminium or zinc?
Soft lead is primarily composed of lead (Pb) and does not contain significant amounts of copper, aluminum, or zinc. It is characterized by its malleability and low melting point. While lead alloys can contain small amounts of other metals for specific properties, soft lead itself is mainly pure lead.
How can zinc be separated from lead in the condenser?
In the blast furnace a mixed lead/zinc sinter is added and the lead bullion is tapped conventionally from the bottom of the furnace while metallic zinc vapour is distilled off and captured/condensed by a spray of molten lead droplets. A solution of zinc and lead leaving the condenser, when cooled this cool zinc can be floated off, while the lead is recirculated to the collector. Zinc being less dense can be continuously removed from the top layers.
The specific gravity of a lead acid cell is often used as a measure of its?
Rate of Discharge
Where is zinc Mined in Australia?
Zinc is always found in combination with lead and silver. The largest lead-zinc-silver mine in Australia is Mount Isa, producing about 4.5 million tonnes silver-lead-zinc ore per annum with concentrations of: 154g/t silver 5.4% lead 6.5% zinc
What is melting point of zinc and lead?
The melting point of zinc is 419.5°C, while the melting point of lead is 327.5°C.
