The logarithm of hydrolysis constant, K1,-1, for the removal of one proton from an aqua ion [M(H2O)n]z+ - H+ ⇌ [M(H2O)n-1(OH)](z-1)+ [ [M(OH)]{(z-1)+ ] = K1,-1 [Mz+] [H+] −1 shows a linear relationship with the ratio of charge to M-O distance,z/d where?

$logK_text(1,-1) = -9.5$

$A = "-19.8"$
$Z= 2$
$d = "213.1 pm" = "2.131 Å"$

$logK_text(1,-1) = A + 11.0 z/d = "-19.8" + 11.0 × 2/2.131 = "-19.8 + 10.32" = "-9.5"$
