Neutralization reactions Flashcards
(25 cards)
What is a neutralization reaction?
A chemical reaction between an acid and a base that produces a salt and water.
True or False: Neutralization reactions always produce carbon dioxide.
False
In a neutralization reaction, what are the products formed?

True or False: All neutralization reactions are exothermic.
True
What is formed when sulfuric acid reacts with sodium hydroxide?
Sodium sulfate and water.
Name a common laboratory use for neutralization reactions.
To neutralize acidic or basic spills.
What is the pH range of acidic solutions?
Less than 7.
Fill in the blank: A base is a substance that accepts _____ in a reaction.

What happens to the pH of a solution during a neutralization reaction?
It approaches 7, indicating neutrality.
Which ion is responsible for the acidic properties of a solution?
Hydrogen ion (H+)
What type of salt is produced from the neutralization of a strong acid and a strong base?
Neutral salt.
True or False: Neutralization reactions can occur in both aqueous and non-aqueous solutions.
True
What is the term for the point at which an acid and base have completely reacted in a titration?
Equivalence point.
In a neutralization reaction, what role does water play?
It is one of the products formed.
What is the result of mixing hydrochloric acid with sodium bicarbonate?
Sodium chloride, water, and carbon dioxide.
Which of the following is NOT a product of neutralization? (a) Water (b) Salt (c) Hydrogen gas
c) Hydrogen gas
Define ‘titration’ in the context of neutralization reactions.
A technique to determine the concentration of an acid or base by reacting it with a known concentration of the opposite.
Fill in the blank: A buffer solution resists changes in pH upon _____ of small amounts of acid or base.
addition
What type of acid is produced in the reaction between sulfuric acid and potassium hydroxide?
