Conjugate Acids and Bases with pH

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 formed when an acid donates a proton (H+).

Front

What is the pH scale?

Back

The pH scale measures the acidity or basicity of a solution, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What is the relationship between pH and pOH?

Back

pH + pOH = 14. This relationship helps to determine the acidity or basicity of a solution.

Front

What is the pH of a neutral solution at 25°C?

Back

The pH of a neutral solution at 25°C is 7.0.

Front

What does a pH less than 7 indicate?

Back

A pH less than 7 indicates that the solution is acidic.

Front

What does a pH greater than 7 indicate?

Back

A pH greater than 7 indicates that the solution is basic.

Front

What is the conjugate base of HCl?

Back

The conjugate base of HCl is Cl-.

Front

What is the conjugate acid of NH3?

Back

The conjugate acid of NH3 is NH4+.

Front

How do you calculate pOH from pH?

Back

To calculate pOH from pH, use the formula: pOH = 14 - pH.
