science acids and bases

What is the pH scale?

0-14 tells strength of acid/bases

What is a hydrogen ion?

An atom of hydrogen that has lost its electron

What is salt?

Any ionic compound that can be made from the neutralization of an acid with a base

What is an acid?

Any substance that produces hydrogen ions in water

What is a base?

Any substance that produces hydroxide ions in water

When the pH of a solution is low, is the concentration of hydrogen ions high or low?

high

What do acids in water separate into?

hydrogen ions

What two substances does a neutralization reaction produce from?

potassium nitrate/salt and water

True or False? A strong acid is safe as long as it's in a dilute solution.

False

True or False? A weak acid produces more OH- ions than a strong acid.

False

True or False? An acid-base mixture is always more acidic than the starting solutions were.

False

What is a hydroxide ion?

Ion gains electrons that are produced by the base

True or False? A strong acid produces more H+ ions than a weak acid.
