pH, pOH, & Neutralization Practice

Front

What is pH?

Back

pH is a measure of the hydrogen ion concentration in a solution, indicating its acidity or alkalinity on a scale of 0 to 14.

Front

What is pOH?

Back

pOH is a measure of the hydroxide ion concentration in a solution, indicating its basicity on a scale of 0 to 14.

Front

What is the relationship between pH and pOH?

Back

pH + pOH = 14.

Front

How do you calculate pH from [H⁺] concentration?

Back

pH = -log[H⁺].

Front

How do you calculate pOH from [OH^-] concentration?

Back

pOH = -log[OH^-].

Front

What is the pH of a solution with [H⁺] = 1 x 10^-2 M?

Back

pH = 2.

Front

What is the pOH of a solution with [OH^-] = 2.7 x 10^-4 M?

Back

pOH = 3.56.

Front

What is an acid?

Back

An acid is a substance that donates hydrogen ions (H⁺) in a solution, resulting in a sour taste.

Front

What is a base?

Back

A base is a substance that accepts hydrogen ions (H⁺) or donates hydroxide ions (OH^-) in a solution, resulting in a bitter taste.

Front

What is neutralization?

Back

Neutralization is a chemical reaction between an acid and a base that produces water and a salt.
