solubility of alkali metal carbonates

solubility of alkali metal carbonates

The carbonates tend to become less soluble as you go down the Group. Solubility of the carbonates. Among the carbonate melts, the class of alkali metal carbonates (Li 2 CO 3, Na 2 CO 3i and K 2 CO 3) and their mixtures are the most prominent.These melts are fairly stable in the temperature range of 400 to 1000°C, exhibit low vapor pressures, can be easily contained in common ceramic and alloy materials, and are environmentally safe. The carbonates of group-2 metals and that of lithium decompose on heating, forming an oxide and carbon dioxide . The solubility of carbonates increases down the group in alkali metals (except ) . These halides can also be prepared by the action of aqueous halogen acids (HX) on metals oxides, hydroxides or carbonate. Alkali metals hydroxides are very strong bases, highly soluble in water and are not decomposed on heating.However, LiOH decomposes on heating to give because latter is more stable than former. There's a certain solubility rule stating all carbonates, phosphates and hydroxides are insoluble unless mixed with hydroxides or alkali metals. The carbonates of alkaline earth metals can be regarded as salts of weak carbonic acid (H 2 CO 3) and metal hydroxide, M(OH) 2. Magnesium carbonate (the most soluble one I have data for) is soluble to the extent of about 0.02 g … M 2 O + 2HX → 2MX + H 2 O . Examples of net ionic equations for the reactions are: Solubility: The solubility of the sulphates in water decreases down the groups i.e. In the presence of carbon dioxide, carbonates dissolve by forming bicarbonates. The carbonates decompose on heating form metal oxide and CO 2 . Carbonates of metal: Thermal stabilityThe carbonates of alkali metals except lithium carbonate are stable to heat. The solubility of carbonates decreases from Be to Ba. Why is this? Carbonates exist as solid and insoluble in water. Solubilities of the halides, nitrates, carbonates, sulfates, and some perchlorates of all the alkali metals and alkaline earth metals in methanol at room temperature have been determined. The alkali metals combine directly with halogens under appropriate conditions forming halides of general formula MX. What makes the alkali metals so special? But carbonates of alkaline earth metals are insoluble in water. Data on some, such as cesium and rubidium fluoride, nitrate, carbonate, and sulfate, appear to be reported for the first time. The stability of carbonates and bicarbonates increases down the group. Be > Mg > Ca > Sr > Ba. Abstract. These carbonates precipitate upon mixing a solution of soluble alkali metal carbonate with a solution of soluble salts of these metals. Properties of Sulphates of Alkali Earth Metals. Alkali metal sulphates are more soluble in water than alkaline earth metals. The sulphates of alkaline earth metals are all white solids. Sulphates. (a) Nitrates (b) Carbonates (c) Sulphates Answer: (a) Nitrates of both group 1 and group 2 elements are soluble in water because hydration energy is more than the lattice energy. Ionic character and the thermal stability of the carbonates increases from Be to Ba. … Their basic strength increases from LiOH to CsOH due to a corresponding decresae in the I.E., of the metal in a group,i.e., the order:- (c)Sulphate-thermal stability is good for both alkali and alkaline earth metals. The carbonates of the alkaline earth metals of group 12 and lead(II) are not soluble. None of the carbonates is anything more than very sparingly soluble. Compare the solubility and thermal stability of the following compounds of the alkali metals with those of the alkaline earth metals. Halides of Alkali Metals.
