Acid & Base pH calculation

Front

What is an Arrhenius acid?

Back

An Arrhenius acid is a substance that produces H+ ions in an aqueous solution.

Front

What is the formula to calculate pH from [H+] concentration?

Back

pH = -log[H+] where [H+] is the concentration of hydrogen ions.

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 is the relationship between pH and [H+] concentration?

Back

As pH decreases, [H+] concentration increases, and vice versa.

Front

What is the [H+] concentration in a solution with a pH of 3?

Back

[H+] = 1 x 10^-3 M.

Front

What is a Bronsted-Lowry acid?

Back

A Bronsted-Lowry acid is a substance that donates a proton (H+) to another substance.

Front

What is a Bronsted-Lowry base?

Back

A Bronsted-Lowry base is a substance that accepts a proton (H+) from another substance.

Front

What is a conjugate acid?

Back

A conjugate acid is the species formed when a base accepts a proton.

Front

What is a conjugate base?

Back

A conjugate base is the species that remains after an acid donates a proton.

Front

What is the pH of a solution with [H+] of 1 x 10^-7 M?

Back

The pH is 7.0.
