An Example of an Isotope Effect Is the Difference in the Dissociation

question 29

Short Answer

An example of an isotope effect is the difference in the dissociation of D₂O compared to H₂O,as shown below.
H₂O(l)⇌ H⁺(aq)+ OH^-(aq)K =1.0 × 10^-14
D₂O(l)⇌ D⁺(aq)+ OD^-(aq)K =2.0 × 10^-15
A neutral H₂O solution has a pH = ________,whereas a neutral D₂O solution has a pH = pD = ________.
