Acid and Bases review

Front

What is pH?

Back

pH is a measure of the acidity or basicity of a solution, calculated as the negative logarithm of the hydrogen ion concentration: pH = -log[H+].

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), the basicity decreases (higher pOH), and vice versa.

Front

What is an acid?

Back

An acid is a substance that donates protons (H+) in a solution and has a pH less than 7.

Front

What is a base?

Back

A base is a substance that accepts protons (H+) or donates hydroxide ions (OH-) in a solution and has a pH greater than 7.

Front

What is the endpoint of a titration?

Back

The endpoint of a titration is the point at which the amount of acid and base are stoichiometrically equivalent, often indicated by a color change.

Front

What is the formula for calculating molarity?

Back

Molarity (M) = moles of solute / liters of solution.

Front

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

Back

pH = -log[H+]. For example, if [H+] = 6.0 x 10^-10 M, then pH = 9.22.

Front

What is the product of an acid-base reaction?

Back

The products of an acid-base reaction typically include water (H2O) and a salt.

Front

What is the significance of the neutralization reaction?

Back

Neutralization reactions between acids and bases produce water and a salt, and they are important in various chemical processes.

Front

What is the pOH of a solution if [OH-] = 2.7 x 10^-4 mol/L?

Back

pOH = -log[OH-]. For [OH-] = 2.7 x 10^-4, pOH = 3.56.
