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"#

The linear relationship between the logarithm of the hydrolysis constant, ( K_{1,-1} ), and the ratio of charge to M-O distance, ( \frac{z}{d} ), occurs in the aqua ion ( [M(H_2O)_n]^z+ ), where ( z ) represents the charge and ( d ) represents the M-O distance.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
