Disposal. Any remaining aqueous lead can be precipitated out of solution by the addition of sodium carbonate. The lead carbonate and lead iodide solids can be filtered for disposal and the remaining solution washed down the drain with plenty of water.

► Exposure to Lithium can cause loss of appetite, nausea, vomiting, diarrhea and abdominal pain. ► Lithium can cause headache, muscle weakness, twitching, blurred vision, loss of coordination, tremors, confusion, seizures and coma.

Treatment for inhalation exposures

1. Ventilate the area. Open the windows and turn on the fan.
2. Leave the area and get fresh air. Fresh air may resolve many uncomfortable symptoms.
3. Treat the symptoms that are not alleviated by the fresh air:

Toxicity. Lead iodide is very toxic to human health. Ingestion will cause many acute and chronic consequences characteristic of lead poisoning. Lead iodide has been found to be a carcinogen in animals suggesting the same may hold true in humans.

They contain two aqueous reactants, one aqueous product, and one solid product. In this reaction, two soluble products, Pb(NO3)2 and KI, combine to form one soluble product, KNO3, and one insoluble product, PbI2. This is a precipitation reaction, and PbI2 is the precipitate.

The reaction is an example of a metathesis reaction, which involves the exchange of ions between the Pb(NO3)2 and KI. The Pb+2 ends up going after the I- resulting in the formation of PbI2, and the K+ ends up combining with the NO3- forming KNO3. NO3- All nitrates are soluble.

possible products from the mixture of AgNO3(aq) and Na3PO4(aq) are Ag3PO4 and NaNO3. It is insoluble and would precipitate from the mixture. Because compounds containing Na+ (and most containing Cl−) are soluble, NaCl is soluble.

If the value of the ion product is greater than the value of the Ksp, then a precipitate will form. The formation of the precipitate lowers the concentration of each of the ions until the ion product is exactly equal to the Ksp, at which point precipitation ceases.

Water

Sodium nitrate is a white deliquescent solid very soluble in water….Sodium nitrate.

Ammonium chloride is a white crystalline solid. It is soluble in water(37%).

Lead sulfate appears as a white crystalline solid. Insoluble in water and sinks in water. Contact may irritate skin, eyes, and mucous membranes.

It is virtually insoluble in water (285 mg/l at 30 °C) and insoluble in alcohol. Its Ksp is 1.1 × 10–10. It is soluble in concentrated sulfuric acid. The crystal structure of BaSO4 is known to be rhombic, with a space group pnma.

Barium sulphate is insoluble in water because it has a high lattice energy. On adding water in barium sulphate its hydration energy decreases more rapidly in comparison to its lattice energy. And to be soluble in water the component lattice energy should be less than its hydration energy.

All sodium, potassium, and ammonium salts are soluble in water. The chlorides, bromides, and iodides of all metals except lead, silver, and mercury(I) are soluble in water. HgI2 is insoluble in water. PbCl2, PbBr2, and PbI2 are soluble in hot water.
