Is HCN a base?
Understand the Problem
The question is asking whether hydrogen cyanide (HCN) is classified as a base. To determine this, we need to consider the properties of HCN and how it behaves in water, mainly if it can accept protons or donate electrons.
Answer
HCN is a weak acid.
The final answer is that HCN is a weak acid.
Answer for screen readers
The final answer is that HCN is a weak acid.
More Information
HCN has a pKa value around 9.21, indicating it is a weak acid. It can donate a proton (H+), forming its conjugate base, CN- (cyanide ion).
Tips
A common mistake is thinking that a compound can only be classified strictly as an acid or a base without considering the context or specific theory (e.g., Bronsted-Lowry).
