Frequently Asked Questions about HNO2 (Nitrous Acid)
Is HNO2 an Acid or Base?
HNO2, nitrous acid, is an acid. It releases H+ (hydrogen-ion) in water. That means, HNO2 has the ability to donate hydrogen-ion. As acid is any compound that can release H+ in water or the one that can give away a proton, HNO2 is labeled as acid too.
Is HNO2 (Nitrous Acid) a Strong or Weak Acid?
HNO2 is a very weak acid. It is because it doesn’t dissociate completely in water. It is very unstable. It mostly exists only in aqueous solutions. Many may mix ‘nitric acid’ (HNO3) and ‘nitrous acid’ (HNO2) because of their similar name or formula. But HNO2 is a weak acid and HNO3 is the strong one.
What is HNO2 commonly used for?
HNO2, also known as nitrous acid, is used with other substances to treat cyanide poisoning. Acute cyanide exposure that causes death within seconds is rare. Most of the cyanide exposure is unintentional. That can become acute when left untreated. HNO2 is also an ingredient in making diazonium salts, which are used for dyeing fabric.

How to Find and Choose a Chemistry Tutor
Instructor Reputation
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.
