Acids, Bases, pH, pOH Titration Test

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 formula to calculate pH?

Back

pH = -log[H+], where [H+] is the concentration of hydrogen ions in moles per liter.

Front

What is a strong acid?

Back

A strong acid is an acid that completely dissociates in solution, releasing all of its hydrogen ions (H+). Examples include HCl and H2SO4.

Front

What is a strong base?

Back

A strong base is a base that completely dissociates in solution, releasing all of its hydroxide ions (OH-). Examples include NaOH and KOH.

Front

What is the relationship between pH and pOH?

Back

pH + pOH = 14. This relationship shows that as the acidity of a solution increases (lower pH), its basicity decreases (higher pOH), and vice versa.

Front

What is titration?

Back

Titration is a laboratory procedure used to determine the concentration of an unknown solution by reacting it with a solution of known concentration.

Front

What is the equivalence point in titration?

Back

The equivalence point is the point in a titration where the amount of titrant added is exactly enough to completely neutralize the analyte solution.

Front

What is a buffer solution?

Back

A buffer solution is a solution that resists changes in pH when small amounts of acid or base are added, typically composed of a weak acid and its conjugate base.

Front

What is the Bronsted-Lowry definition of an acid?

Back

According to Bronsted-Lowry, an acid is a substance that donates a hydrogen ion (H+) to another substance.

Front

What is the Bronsted-Lowry definition of a base?

Back

According to Bronsted-Lowry, a base is a substance that accepts a hydrogen ion (H+) from another substance.
