Description. Potassium iodide is highly soluble in water so SSKI is a concentrated source of KI. Chloride compounds can conduct electricity when fused or dissolved in water. Rubidium iodide is a salt with a melting point of 642 Â°C. Applications. Gerhold Chemetals Co., Ltd supply the nano materials Rubidium… About 400.000 tonnes of iodine escape from the oceans every year as iodide in sea spray or as iodide, hydrichloric acid and methyl iodide, produced by marine organisms. Life Science. Unless specified, the acetone is considered anhydrous. Rubidium oxide is the chemical compound with the formula Rb 2 O. Rubidium oxide is highly reactive towards water, and therefore it would not be expected to occur naturally. Start studying Solubility rules. Despite the stability and solubility of Rb+ and its compounds, it displays The rubidium content in minerals is often calculated and quoted in terms of Rb 2 O.

CRC Handbook of Chemistry and Physics, 77th edition Rubidium is the first alkali metal in the group to have a density higher than water, so it sinks, unlike the metals above it in the group. Salts of Bromide, Chloride and iodide are said to be water soluble except in case of cations such as silver, lead and mercury. This alkali metal halide is composed of rubidium and chlorine, and finds diverse uses ranging from electrochemistry to molecular biology. (For safety reasons, an excess of potassium iodide is used to ensure all of the soluble lead is reacted away). Specpure® Ion Chromatography Standards.
