Facts about Bases
- 10
Ammonia solutions with concentrations above 25% by weight become increasingly caustic, reaching pH levels of 13 or higher and causing severe skin damage upon contact.
- 09
Lye, a traditional base used for centuries in soap-making and food preparation, can cause severe chemical burns because it penetrates skin tissue more deeply than acids of equivalent strength.
- 08
Antacids like aluminum hydroxide and magnesium hydroxide neutralize stomach acid by accepting protons, providing relief within 5 to 15 minutes of ingestion.
- 07
Magnesium hydroxide, found in seawater at concentrations around 1.3 grams per liter, is extracted industrially to produce over 1 million metric tons annually for use in water treatment and flame retardants.
- 06
In 1923, chemist Johannes Brønsted defined bases as proton acceptors, revolutionizing acid-base theory beyond the earlier Arrhenius definition limited to hydroxide-producing substances.
- 05
Potassium hydroxide, used in soap production since ancient Egypt, dissolves in water 121 times more readily than sodium hydroxide at room temperature.
- 04
Ammonia, a weak base produced by decomposing organic matter, contains 17% nitrogen by mass and serves as the primary ingredient in approximately 80% of all synthetic fertilizers worldwide.
- 03
Calcium hydroxide, commonly called slaked lime, has been used in construction for over 4,000 years and remains a key ingredient in modern concrete and mortar production.
- 02
Sodium hydroxide, a common industrial base, can reach temperatures of 98°C when dissolved in water due to its highly exothermic reaction.
- 01
The pH scale, which measures base strength, ranges from 0 to 14, with values above 7 indicating basic solutions like ammonia at pH 11.6.
