Nearly all salts are strong electrolytes. Therefore, salts exist entirely of ions in solution.

Acid-Base Properties of Salt Solutions. Nearly all salts are strong electrolytes. Therefore, salts exist entirely of ions in solution. Acid-base properties of salts are a consequence of the reaction of their ions in solution.

16.8: Relationship Between K a and K b

16.8: Relationship Between K a and K b. To quantify the relationship between strength of acid and conjugate base, recall multistep equilibria: Reaction 1 + reaction 2 = reaction 3 has. For a conjugate acid-base pair, Therefore, the larger the K a , the smaller the K b

The rate-determining step

The rate-determining step. L.O.: What is the rate-determining step of a reaction? What is the connection between the rate equation for a reaction and the mechanism?. Discuss in pairs any of these two situations. Think what are the steps involved and which one is the slowest step.
