Studying chemistry involves learning about acids and bases. If you’re taking a chemistry class, you’ll probably need to memorize the strong acids and bases. Use this list of strong acids and bases as a tool to help you learn the names and chemical composition of each one.
Standard List of Strong Acids and Bases
List of Strong Acids
Strong acids are not named as such because they are more powerful than other acids. A strong acid is one that dissolves in water. The term strong in the name refers to the acid’s ability to release hydrogen (H+) molecules, which allows it to become ionized when placed into a solution of water. Weak acids do not have this ability. There are seven strong acids.
These are all highly corrosive substances that can produce dangerous fumes and cause extremely painful burns. These substances must be handled with extreme care.
How to Memorize Strong Acids
Memorizing a list of substances can be challenging. Try this combination of a mnemonic device paired with chunking to help commit the list of seven strong acids to memory.
Strong Acids Mnemonic Device
Use the phrase “Chemistry needs preparation sometimes, help!” to get started memorizing the seven strong acids.
chemistry - chloric acid
needs - nitric acid
preparation - perchloric acid
sometimes - sulfuric acid
help - hydro acid
Add on the chunking tip below to complete your memorization of the strong acids, since several of the items start with the same prefix.
Chunking and a Mnemonic
In the list of strong acids, there are three h words, each starting with the prefix hydro. Chunk those three words together and learn the phrase “before in class” to help remember them. This phrase is based on the letter immediately following the hydro- in the remaining strong acids.
To recall the acids that start with the letter h, ask yourself, “When is help needed?” The answer is:
before - hydrobromic
in - hydroiodic
class - hydrochloric
Usage Examples for Each Strong Acid
If you want to know more about the strong acids than just what they’re called and their chemical composition, you may find these examples of ways each one can be used interesting and informative.
chloric acid - chloride salts manufacturing, match production, explosives production
hydrobromic acid - industrial cleaning products, lithographic printing, engraving
hydrochloric acid - stomach acid (aids in digestion), fireworks production, battery production
hydroiodic acid - acetic acid production, sanitizing medical tools, Industrial reducing agent
nitric acid - explosives production, ammonium nitrate (fertilizer), polyurethane production
perchloric acid - separating sodium from potassium, rocket fuel production, explosives production
sulfuric acid - drain cleaner ingredient, wastewater treatment, steel manufacturing
Each of these acids can be used in many ways beyond the examples provided above. Most of their usage applications are specific to industrial and scientific laboratory settings.
List of Strong Bases
Like strong acids, strong bases also dissolve thoroughly in water, as opposed to weak bases that do not dissolve. Strong bases release hydroxide (OH-) ions and absorb hydrogen (H+) molecules. There are eight strong bases.
Extreme caution should be used when working with these substances. They are highly corrosive and can cause extremely dangerous chemical burns.
How to Memorize Strong Bases
To help remember and recall the eight strong bases, try the mnemonic device below. Note that it includes the words base, and strong, so it should be easy to associate the phrase with what it represents.
bases - barium
can - calcium
certainly - cesium
look - lithium hydroxide
pleasing - potassium hydroxide
really - rubidium hydroxide
something - sodium hydroxide
strong - strontium hydroxide
Please note that where there are two strong bases that start with the same letter, the corresponding word in the mnemonic starts with the first two letters or the corresponding word to help make the memorization tool as helpful as possible.
Usage Examples for Each Strong Base
Are you wondering about how the strong bases can be used? Discover a few examples of practical applications for each one.
barium hydroxide - glass manufacturing, grease additive, pesticide production
calcium hydroxide - dental fillings, food processing (pickling lime), wastewater treatment
cesium hydroxide - electric storage batteries, metal production, radioactive waste clean-up
lithium hydroxide - lithium ion batteries, lubricant (grease) production, soap manufacturing
potassium hydroxide - desiccant, detergent ingredient, liquid fertilizer production
rubidium hydroxide - electric storage batteries, rubidium crystals production, wastewater treatment
sodium hydroxide - lye, drain cleaner ingredient, oven cleaner ingredient
strontium hydroxide - grease manufacturing, soap manufacturing, extracting sugar from beets
The strong bases have many uses beyond the examples listed above. These substances have numerous applications in industrial and scientific settings.
