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