Is HCN a strong or weak acid?
Understand the Problem
The question is asking whether HCN (hydrogen cyanide) is classified as a strong or weak acid, which involves understanding its dissociation in water and its strength compared to other acids.
Answer
HCN is a weak acid.
The final answer is HCN is a weak acid.
Answer for screen readers
The final answer is HCN is a weak acid.
More Information
Hydrogen cyanide (HCN) dissociates only partially in solution, hence it is classified as a weak acid. Its conjugate base, CN-, is relatively strong and binds strongly to protons.
Tips
Common mistakes might include assuming HCN is strong just because it is toxic. Toxicity and acid strength are different properties.
