Anomalous Behaviour Of Lithium

Step 1: Reactivity of alkali metals increases down the group.
Step 2: Cesium has the lowest ionization energy.

Step 1: Calcium chloride is produced during regeneration of ammonia.

is produced as a by-product in Solvay ammonia process:



Sodium carbonate is manufactured by Solvay ammonia process. The raw materials are brine , ammonia and carbon dioxide.

Step 1: Acidity of hydrides increases down the group: NH₃ < PH₃ < AsH₃ (correct) Step 2: Basic nature of oxides increases from amphoteric to strongly basic: Al₂O₃ < MgO < CaO < K₂O (correct) Step 3: Ionic radius increases down the group: Li⁺ < Na⁺ < K⁺ < Cs⁺ (correct) Step 4: Order given in option (B) is incorrect.
