Nuetralisation Flashcards
What is a neutralisation reaction?
A neutralisation reaction is a chemical reaction in which an acid and a base react to form water and a salt.
Fill in the blank: The products of a neutralisation reaction are ______ and ______.
water; salt
True or False: All neutralisation reactions result in a pH of 7.
False
What type of reaction occurs when hydrochloric acid reacts with sodium hydroxide?
Neutralisation reaction
What is the general equation for a neutralisation reaction?
Acid + Base → Salt + Water
Which of the following is a common indicator used to determine the endpoint of a neutralisation reaction? A) Phenolphthalein B) Methyl Orange C) Both A and B
C) Both A and B
What is formed when sulfuric acid reacts with potassium hydroxide?
Potassium sulfate and water
True or False: Neutralisation reactions are exothermic.
True
What happens to the pH of a solution during a neutralisation reaction?
The pH approaches 7 as the acid and base neutralise each other.
Identify the acid in the neutralisation reaction: HCl + NaOH → NaCl + H2O.
HCl
What is the term for the salt produced when nitric acid reacts with sodium hydroxide?
Sodium nitrate
Fill in the blank: In a neutralisation reaction, an acid donates ______ and a base accepts ______.
protons; protons
What is the role of an indicator in a neutralisation reaction?
To signal the endpoint of the reaction by changing color.
Which of the following is NOT a strong acid? A) HCl B) H2SO4 C) CH3COOH
C) CH3COOH
True or False: A strong acid will completely dissociate in water.
True
What type of salt is formed from the neutralisation of a strong acid and a strong base?
Neutral salt
What is the primary use of neutralisation reactions in everyday life?
To treat acid spills or to balance pH in various applications.
In a neutralisation reaction, what is the effect of adding excess acid or base?
It shifts the pH away from neutrality.
What is the term for the process of adding acid to a base until neutralization occurs?
Titration
What is produced when acetic acid reacts with sodium bicarbonate?
Sodium acetate, water, and carbon dioxide
Fill in the blank: Neutralisation reactions can be used in ______ and ______ applications.
medical; industrial
What is the net ionic equation for the neutralisation of HCl with NaOH?
H⁺ + OH⁻ → H2O
Identify the base in the reaction: H2SO4 + 2NaOH → Na2SO4 + 2H2O.
NaOH
Which property of acids is neutralised by bases?
Acidity
