solubility order of alkali metal nitrates

(a) The mobilities of the alkali metal ions in aqueous solution are Li+ < Na+ Na – Hg + 2H20 (b) What happens when alkali metals are dissolved in ammonia? The hydroxides and carbonates of sodium and potassium are easily soluble in water while the corresponding salts of magnesium and calcium are sparingly soluble in water. Question 10. (i) Sodium metal (ii) Sodium hydroxide Li+ ion has the highest polarising power. Alkali metals due to lower ionization enthalpy are more electropositive than the corresponding group 2 elements. They have a strong tendency to lose 1 electron to form unipositive ions. (a) Sr (b) Ca (c) Be (d) Mg Comment on each of the following observations: Therefore, Lattice energy of Na2CO3 is higher than that of Li2CO3. Thus they show an oxidation state of +1 and are strongly electropositive. Therefore alkali metals are prepared by electrolysis of their fused chlorides. Both the elements have the tendency to form covalent compounds. (iii) Na2O2 + 2H20 ———> 2NaOH + H2O2. This means that their lattice enthalpies are more as compared to the compounds of sodium and potassium. (a) and (d) 7. Question 15. This substance does not exist; it cannot be isolated as a pure substance. In the Solvay process Explain the following: Answer: Due to smallest size, Li+ can polarize water molecules easily than the other alkali metal ions. Ans. All Alkali metals and Ammonium compounds are soluble. How would you prepare sodium silicate from silica? Berrylium hydroxide ( Be(OH) 2) and magnesium hydroxide ( Mg(OH) 2) are completely insoluble in water. From Li to Cs, thermal stability of carbonates increases. Question 17. Data on some, such as cesium and rubidium fluoride, nitrate, carbonate, and sulfate, appear to be reported for the first time. Lithium nitrate on heating evolves O 2 and NO 2 and forms Li 2 O while other alkali metal nitrates on heating evolve and form their respective nitrites. Question 27. Lithium shows a diagonal relationship with This means that the magnitude of hydration enthalpy is quite large. Na (am) + e- (am) + NH3(l) ——–> NaNH2(am) + —1/2 H2(g). Down the group thermal stability of nitrates increases. (c) Na2O and CO2 Thus Lil– has more covalent character than LiF. (c) Sodium is found to be move useful than potassium? Answer: (a) Na2CO3 is a salt of a weak acid, carbonic acid (H2CO3) and a strong base NaOH. What is the general name for elements of group 1 ? Essentially, all alkali metal (Li +, Na +, K +, Rb +, Cs +) and ammonium (NH 4 +) salts are soluble. (b) high lattice enthalpy. Which electrolyte is used to obtain sodium in Castner’s process? Question 17. Indeed, I found one website with four terms. Describe the importance of the following: Alkali metals exhibit +1 oxidation states in their compounds. All nitrates are soluble. To start, watch as we mix various metal nitrates and Alkali metal salts. Question 12. Explain the significance of sodium, potassium, magnesium and calcium in biological fluids. (iii) Quick lime At cathode: For example, a typical Group 2 nitrate like magnesium nitrate decomposes like this: In Group 1, lithium nitrate behaves in the same way - producing lithium oxide, nitrogen dioxide and oxygen. (a) Why Cs is considered as the most electropositive element? Question 5. The exceptions are the alkali metal hydroxides and Ba (OH) 2. (a) sodium (b) silicon (c) nitrogen (d)magnesium What do you mean by diagonal relationship in periodic table? Alkaline earth metals are In the vapour state, it exists as a chlorobridged dimer. (b) It is used in glass manufacturing. Part 2. Answer: Li2CO3 is a covalent compound whereas Na2CO3 is an ionic compound. Answer: NaOH is more basic. Which statement is true? Question 2. (ii) Basicity of oxides. 1. Nitrates. Of these metals are insoluble in water because its hydration energy v ) solubility in ammonia.
