Acids/Bases/pH/Salts

Front

What is an electrolyte?

Back

An electrolyte is a substance that conducts electricity when dissolved in water, typically found in acids, bases, and salts.

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 an acid?

Back

An acid is a substance that donates hydrogen ions (H+) in a solution, typically having a pH less than 7.

Front

What is a base?

Back

A base is a substance that accepts hydrogen ions (H+) or donates hydroxide ions (OH-) in a solution, typically having a pH greater than 7.

Front

What is a salt?

Back

A salt is a compound formed from the reaction of an acid and a base, consisting of cations and anions.

Front

What does a pH of 1 indicate?

Back

A pH of 1 indicates a very high concentration of hydrogen ions (H+), making the solution highly acidic.

Front

What does a pH of 9 indicate?

Back

A pH of 9 indicates a basic solution, with a lower concentration of hydrogen ions (H+) and a higher concentration of hydroxide ions (OH-).

Front

What is the relationship between pH and hydrogen ion concentration?

Back

As pH decreases, the concentration of hydrogen ions (H+) increases, and vice versa.

Front

What is the formula for calculating pH?

Back

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

Front

What is the significance of a neutral pH?

Back

A neutral pH of 7 indicates that the concentrations of hydrogen ions (H+) and hydroxide ions (OH-) are equal.
