Frequently Asked Questions about KOH (Potassium Hydroxide)
Is KOH (Potassium Hydroxide) an Acid or Base?
KOH, potassium hydroxide, is a base. It releases OH– (hydroxide-ion) in water. This very hydroxide-ion accepts a proton from acid to make water and salt. These characteristics of releasing OH– or accepting proton or reacting with an acid etc. makes KOH a base. In fact, it’s a strong base as it can completely dissociate in water.
Is KOH a Strong or Weak Acid/Base?
KOH (potassium hydroxide) is a strong base. It usually has a high pH of 10-13. Since it releases OH– and dissociates thoroughly in water too, KOH is considered a strong base. With its combination with strong acid HCl ( hydrochloric acid), KOH produces water and neutral salt KCl (potassium chloride).
What is KOH commonly used for?
KOH (potassium hydroxide), commonly known as caustic potash, is one of the ingredients in soaps. Sometimes it is used in place of NaOH as KOH can cut through oil faster because of being smaller than NaOH. KOH can control the pH of the soil to help the crops grow better.

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.
