Acid-Base Review

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.

What does a pH of 2 indicate about a substance?

Back

A pH of 2 indicates that the substance is highly acidic and can react with metals to produce hydrogen gas.

Front

How do you calculate pH from hydrogen ion concentration?

Back

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

Front

What is the pH of a solution with [H+] = 1 × 10^{-3} M?

Back

The pH of the solution is 3.

Front

What is the typical pH range for sour-tasting substances found in citrus fruits?

Back

The typical pH range for sour-tasting substances in citrus fruits is 0-3.

Front

What is the relationship between pH and [OH-]?

Back

The relationship is given by the equation: pH + pOH = 14, where pOH = -log[OH-].

Front

What is the pH of a solution with a pOH of 3.5?

Back

The pH of the solution is 10.5, calculated as 14 - 3.5.

Front

How do you determine the acidity or basicity of a substance?

Back

You can determine acidity or basicity by measuring its pH; lower pH values indicate acidity, while higher values indicate basicity.

Front

What is the pH of baking soda?

Back

The pH of baking soda is approximately 9, indicating it is basic.

Front

What is the pH of bleach?

Back

The pH of bleach is approximately 12, indicating it is highly basic.
