Sale and use of only green firecrackers which do not use barium salts or compounds of antimony lithium mercury arsenic lead or strontium chromate in Punjab. Two days after prohibiting the use of any kind of firecrackers in Mandi Gobindgarh and Jalandhar the state government has revised its decision throw. Sulfides formed with group 2 cations and hydroxides formed with calcium strontium and barium are exceptions.
If the rules state that an ion is soluble then it remains in its aqueous ion form. If an ion is insoluble based on the solubility rules then it forms a solid with an ion from the other reactant. If all the ions in a reaction are shown to be soluble then no precipitation reaction.

Stable with most metals and inorganic anions forming insoluble silicate carbonate hydroxide oxide fluoride sulfate oxalate chromate arsenate and tungstate in neutral aqueous media. 2-100 ppb levels stable for months in 1 HNO 3 LDPE container. 1-10000 ppm solutions chemically stable for years in 1-10 HNO 3 LDPE container.
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a silvery-greyish appearance when oxidation is removed. It is the first element in group 12 IIB of the periodic tableIn some respects zinc is chemically similar to magnesium.
Both elements exhibit only one normal oxidation state 2 and the Zn 2 and Mg 2 ions.

The atomic weight of strontium is approximately equal to the average of the atomic weights of calcium and barium.
Later on in 1829 he discovered the halogen triad and alkali metal triad consisting of Cl Br and I and Li Na and K and proposed that nature contained triads of elements with similar chemical properties and the atomic weight of the second element of the triad is the average.
