Order of mobility of alkali metal ions
Witryna26 lis 2024 · The most important factor in the coordination of various macrocyclic ligands to alkali metal ions is the relative size of the ion and the ligand cavity. For example, 4,7,13,16,21,24-hexaoxa-1,10diazabicyclo[8,8,8]hexacosane is a potentially octa-dentate ligand; however, the binding eciency is very dependant on the identity of the M+ ion … WitrynaThe correct order of the mobility of the alkali metal ions in aqueous solution i AIPMT 2006 s-Block Elements Chemistry NEET.

(c) (where M = Ca, Sr or Ba) is nearly constant. Answer : (a) On moving down the alkali group, the ionic and atomic sizes of the metals increase. The given alkali metal ions can be arranged in the increasing order of their ionic sizes as: Li + < Na + < K + < Rb + < Cs + bushnell custom 600 range finderWitryna4 lip 2024 · The alkaline earth metals are produced for industrial use by electrolytic reduction of their molten chlorides, as indicated in this equation for calcium: (20.5.2) C … bushnell crossbow scopeWitrynaThe given alkali metal ions can be arranged in the decreasing order of their hydrations as: Li + > Na + > K + > Rb + > Cs + Greater the mass of a hydrated ion, the lower is its ionic mobility. Therefore, hydrated Li + is the least mobile and hydrated Cs + is the most mobile. Thus, the given alkali metal ions can be arranged in the increasing ... handi quilter prewound bobbinsWitryna28 sie 2016 · So smaller ions have a larger solvation shell than larger ions (assuming they carry the same charge). This is the reason why mobilities of alkali metal ions increase from $\ce{Li^+}$ to $\ce{Cs^+}$ (and not the other way around); the lithium ions are effectively dragging a large amount of solvent molecules with them and thus, … handi quilter pro stitcher liteWitrynaSolution.
