Equilibrium problems involving

A typical equilibrium problem involves finding the equilibrium concentrations (or pressures) of reactants and products, given the value of the equilibrium constant and the initial concentrations (or pressures). 

This problem illustrates all the important steps required for solving a typical equilibrium problem involving a weak acid. These steps are summarized below. 

Just as you saw in Chapter 17 for equilibrium problems in general, there are two types of equilibrium problems involving weak acids and their conjugate bases ... 

The second type of equilibrium problem involving weak acids gives some concentration data and the value and asks for the equilibrium concentration of some component. Such problems are very similar to those we solved in Chapter 17 in which a substance with a given initial concentration reacted to an unknown extent (see Sample Problems 17.6 to 17.8). 

Two common types of weak-acid equilibrium problems involve finding Kg from a concentration and finding a concentration from Kg. We summarize the information in a reaction table, and we simplify the arithmetic by assuming (1) is so... 

A typical equilibrium problem Involves finding the equilibrium concentrations (or pressures) of reactants and products, given the value of the equilibrium constant and the initial concentrations (or pressures). However, since such problems sometimes become complicated mathematically, we will develop useful strategies for solving them by considering cases for which we know one or more of the equilibrium concentrations (or pressures).

How Do I Solve Equilibrium Problems Involving Complex Ion Formation ... 

Matty of the equilibiiiun problems we encounter involve equilibrium constants, such as K, and Ksp, that are very small. Often, this enables us to neglect the unknown x in the denominator of the equilibrium expression, which simplifies the math necessary to solve the problem [ Section 16.5], The solution of an equilibrium problem involving complex ion formation is complicated both by the magnitude of and by the stoichiometry of the reaction. Consider the combination of aqueous copper(II) ions and ammonia to form the complex ion Cu(NH3)4 ...
