Conjugate Acids and Bases with pH

Front

What are acids?

Back

Corrosive substances characterized by a strong smell, a sour taste, and the ability to donate a H+ ion.

Front

What is a conjugate acid?

Back

The species formed when a base gains a proton (H+).

Front

What is a conjugate base?

Back

The species that remains after an acid donates a proton.

Front

What is the pH scale?

Back

A logarithmic scale used to measure the acidity or basicity of a solution, ranging from 0 (acidic) to 14 (basic), with 7 being neutral.

Front

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

Back

7.

Front

What is the relationship between acids and their conjugate bases?

Back

When an acid donates a proton, it forms its conjugate base.

Front

What is the relationship between bases and their conjugate acids?

Back

When a base accepts a proton, it forms its conjugate acid.

Front

What is an example of a strong acid?

Back

Hydrochloric acid (HCl).

Front

What is an example of a weak acid?

Back

Acetic acid (CH3COOH).

What is an example of a strong base?

Back

Sodium hydroxide (NaOH).
