Acids and Bases survery

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 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 a neutral substance?

Back

A neutral substance has a pH of 7, meaning it is neither acidic nor basic, like pure water.

Front

What happens when an acid and a base react?

Back

When an acid and a base react, they undergo a neutralization reaction, producing water and a salt.

Front

What is hydrobromic acid (HBr)?

Back

Hydrobromic acid is a strong acid formed by dissolving hydrogen bromide in water.

Front

What is sodium hydroxide (NaOH)?

Back

Sodium hydroxide is a strong base commonly used in various chemical applications.

Front

What is the product of mixing HBr and NaOH?

Back

The products are water (H2O) and sodium bromide (NaBr).

Front

What is the significance of a pH of 7?

Back

A pH of 7 indicates a neutral solution, meaning it is balanced and does not favor acidity or basicity.

Front

What is the difference between strong and weak acids?

Back

Strong acids completely dissociate in water, while weak acids only partially dissociate.
