Chemical Equilibrium and Acid Base Review

Front

What is pH?

Back

pH is a measure of the acidity or basicity of a solution, defined as the negative logarithm of the hydrogen ion concentration. A pH of 7 is neutral, below 7 is acidic, and above 7 is basic.

Front

What is pOH?

Back

pOH is a measure of the hydroxide ion concentration in a solution, defined as the negative logarithm of the hydroxide ion concentration. It is related to pH by the equation: pH + pOH = 14.

Front

How do you calculate pOH from pH?

Back

pOH can be calculated using the formula: pOH = 14 - pH.

Front

What is the pH range for acids?

Back

The pH range for acids is from 0 to 6.9.

Front

What is the pH range for bases?

Back

The pH range for bases is from 7.1 to 14.

Front

What is dynamic equilibrium in a chemical reaction?

Back

Dynamic equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction, resulting in constant concentrations of reactants and products.

Front

What is a conjugate acid?

Back

A conjugate acid is the species formed when a base gains a proton (H+).

Front

What is a conjugate base?

Back

A conjugate base is the species that remains after an acid donates a proton (H+).

Front

What is the relationship between acids and bases in a neutralization reaction?

Back

In a neutralization reaction, an acid reacts with a base to produce water and a salt.

Front

What is Le Chatelier's Principle?

Back

Le Chatelier's Principle states that if a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change and restore a new equilibrium.
