Paiye sabhi sawalon ka Video solution sirf photo khinch kar. Data on some, such as cesium and rubidium fluoride, nitrate, carbonate, and sulfate, appear to be reported for the first time. CsI has also low solubility due to smaller hydration energy of its two ions. Halite is the mineral form of sodium chloride. Some low-oxidation state transition metals have halides which dissolve well in water, such as ferrous chloride, nickelous chloride, and cupric chloride. 5) For the same alkali metals, the melting point decrease in the order : Fluoride > Chloride > bromide> iodide.
