Beryllium and magnesium do not give colour to flame whereas other alkaline earth metals do so. Why?
Explain why alkali and alkaline earth metals cannot be obtained by chemical reduction methods?
How would you explain the following observations?
(i) BeO is almost insoluble but BeSO4 in soluble in water,
(ii) BaO is soluble but BaSO4 is insoluble in water,
(iii) LiI is more soluble than KI in ethanol.
When an alkali metal dissolves in liquid ammonia the solution can acquire different colours. Explain the reasons for this type of colour change.
Arrange the foll in inc basic nature H2O OH- CH3OH CH3O- . Pls explain on what basis they can be done and also explain using the oxidation state methodArrange in inc order of acid strength HCO3- H3O+ HSO4- HSO3F also pls explain
Arrange the following alkali metal chlorides in the decreasing stability order
LiCl, KCl, NaCl, CsCl
Please explain briefly with reason .
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. Explain.
Why is Na less reactive than K?
why boric acid acts as a strong acid in presence of glycerol?
in vapour phase BeCl2 exist as dimer. What is dimer?
Why is Li2CO3 decomposed at a lower temperature whereas Na2CO3 at higher temperature?
Hydrogen is placed at the top of periodic table and not in the group-1, why?

2.LiI is more soluble than KI in ethanol.Explain.
3.The solubility of alkaline earth metal hydroxides in water increases down the group?
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. Explain.
Why is Na less reactive than K?
why boric acid acts as a strong acid in presence of glycerol?
1) BeCl2 is soluble in organic solvents .
2) Enthalpy of hydration of alkaline earth metals decreases down the group.
