Frequently Asked Questions about HCN (Hydrogen Cyanide)
Is HCN (Hydrogen Cyanide) an Acid or Base?
HCN (Hydrogen cyanide) is an acid. Going by definitions, a substance that releases H+ (hydrogen-ion) in aqueous solution is an acid according to Arrhenius theory. Since HCN does so and it is capable of donating a proton, it is considered an acid. The amount of released H+ (hydrogen-ion) is small. Thus, HCN is labeled as a weak acid.
Is HCN a Strong or Weak Acid?
HCN (Hydrogen cyanide) is a weak acid. According to theories, any acid that dissociates partially in aqueous solution is classified as a weak acid. Because the dissociation of HCN is partial in aqueous solution, it is a weak acid too. It releases a very small amount of hydrogen-ion in water.
What is HCN (Hydrogen Cyanide) commonly used for?
HCN (Hydrogen cyanide) is used in gold and silver mining. It is also used for electroplating metals. You will see its use in the making of plastic, synthetic fibers, dyes etc. In addition, it is an ingredient of pesticides. That way, it plays an important role in the food production system.

How to Find and Choose a Chemistry Tutor
In addition to finding a teacher with good ratings, consider several factors when choosing your chemistry teachers, such as the location, teacher punctuality, diversity of teaching styles, and personality fit. The cost of chemistry lessons often aligns with the teacher’s expertise.
Experience and Specialization of the Teacher
Chemistry teachers sometimes prefer one topic over another, so take advantage of the tutor interview process to understand if they are a good fit. You will want to ensure to find the right fit and price ranges. Just because a teacher is good at chemistry, this is no indication of their ability to teach you or your child.
Virtual VS On-Site Chemistry Lessons
Today, most chemistry lessons occur over online video. However, depending on the lesson, including organic chemistry, inorganic chemistry, chemical reactions, quantum mechanics, inorganic compounds, atomic structure, organic reactions, etc., many teachers are willing to provide safe sessions in person if they are located nearby.
