Frequently Asked Questions about Nitric Acid
Is HNO3 an Acid or Base?
HNO3 , nitric acid, is an acid. It gets separated into hydrogen ions (H+) and nitrate ions (NO3–) in water. When we go by the definition, acid is any substance that releases H+ in an aqueous solution. As nitric acid does so, it is classified as an acid.
Is Nitric Acid a Strong or Weak Acid?
Nitric acid is a strong acid. The more an acid dissociates in aqueous solution, the stronger an acid is classified as. And nitric acid completely dissociates in water by breaking into hydrogen ions and nitrate ions. In addition, nitric acid has an increased polarity and weaker bond between ions that makes it easier to dissociate.
What is Nitric Acid Commonly Used For?
The most common use of nitric acid is for producing fertilizers like ammonium nitrate and calcium nitrate. Not only in making food, it plays an important role in national defense as well by being an ingredient of explosives like nitroglycerin, TNT. If we go in more detail, nitric acid is used for cleaning metals too.

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.
