Frequently Asked Questions about NH4+ (Ammonium-ion)
Is NH4+ an Acid or Base?
NH4+ (Ammonium-ion) is an acid. Any substance that can give away a proton is called an acid according to Bronsted-Lowry theory. Since NH4+ does so too, it is an acid. It releases H+ (hydrogen-ion) while dissolving in water. That is a characteristic of an acid.
Is NH4+ a Strong or Weak Acid?
NH4+ (Ammonium-ion) is a weak acid. When we go by the definition, an acid that dissociates partially in aqueous solution is a weak acid. The more the dissociation is, the more powerful the acid is. But NH4+ doesn’t dissociate completely in water. That’s why it is a weak acid.
What is NH4+ (Ammonium-ion) commonly used for?
NH4+ (Ammonium-ion) is one of the sources of nitrogen used in agricultural areas. Interestingly, NH4+ plays an important role in making our body function properly. Our body uses NH4+ to maintain acid-base balance. This helps to keep us healthy as most enzymes can only work at a certain level of pH.

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.
