1.

Arrange the following as indicated:(i) BeSO_(4), MgSO_(4).. CaSO_(4). SrSO_(4), BaSO_(4)(increasing order of solubility) (ii) Be(OH)_(2), Mg(OH)_(2) Ca(OH)_(2)(increasing of solubility) (III) BeCO_(3). MgCO_(3) CaCO_(3), (increasing stability) (iv) BeCl_(2), MgCl_(2), CaCl_(2), SrCl_(2) (increasing lattice energy) (v) BeCl_(2), MgCl_(2), CaCl_(2), SrCI_(2) (increasing order of hydrolysis)

Answer»
