Acids & Bases Review

Front

What is an acid?

Back

An acid is a substance that donates protons (H+) in a chemical reaction. Acids have 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 chemical reaction. Bases have a pH greater than 7.

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 a conjugate acid?

Back

A conjugate acid is the species formed when a base gains a proton (H+).

Front

What is a conjugate base?

Back

A conjugate base is the species formed when an acid donates a proton (H+).

Front

What is the relationship between pH and pOH?

Back

pH + pOH = 14. This relationship helps to determine the acidity or basicity of a solution.

Front

What is the formula to calculate pOH?

Back

pOH = -log[OH-], where [OH-] is the concentration of hydroxide ions.

Front

What is the significance of a pH of 7?

Back

A pH of 7 indicates a neutral solution, meaning it is neither acidic nor basic.

Front

What are some common properties of acids?

Back

Acids taste sour, turn blue litmus paper red, and react with metals to produce hydrogen gas.

Front

What are some common properties of bases?

Back

Bases taste bitter, feel slippery, and turn red litmus paper blue.
