It is important that you don't confuse the words strong and weak with the terms concentrated and dilute.. As you will see below, the strength of an acid is related to the proportion of it which has reacted with water to produce ions. There are 7 strong acids: chloric acid, hydrobromic acid, hydrochloric acid, hydroiodic acid, nitric acid, perchloric acid, and sulfuric acid. Being part of the list of strong acids doesn’t give any indication of how dangerous or damaging an acid is though. What makes them "strong" is the fact that they completely dissociate into their ions (H + and an anion) when they are mixed with water. In chemistry, there are seven "strong" acids. If it does not dissociate 100%, it is a weak acid. As it turns out, there are very few strong acids, which are given in Table \(\PageIndex{1}\). There are only a few (7) strong acids, so many people choose to memorize them. All the other acids are weak. These acids are often used in industry and everyday life. Learn vocabulary, terms, and more with flashcards, games, and other study tools. If an acid is not listed here, it is a weak acid. As a part of this it defines and explains what is meant by pH, K a and pK a.. Strong acids completely dissociate into their ions in water, while weak acids only partially dissociate. It may be 1% ionized or 99% ionized, but it is still classified as a weak acid. Every other acid is a weak acid.Because there are only seven strong acids, it is easy to commit the list to memory. This page explains the terms strong and weak as applied to acids. Acids and bases that are completely ionized when dissolved in water are called strong acids and strong bases There are only a few strong acids and bases, and everyone should know their names and properties. Start studying 7 strong acids. Any acid that dissociates 100% into ions is called a strong acid.
