Bases are pure substances like sodium hydroxide (NaOH), forming OH− ions in water and having a pH value above 7, while lyes are their aqueous solutions; when bases and acids react, they neutralize each other to produce harmless substances like water (H₂O) and table salt (NaCl). Sodium hydroxide (NaOH) is a significant base used in everyday life, found in drain cleaners for its corrosive properties, while milder alkaline solutions like soaps and detergents are commonly utilized.
Insights
- Bases are pure substances like sodium hydroxide, while lyes are their aqueous solutions, both having a pH greater than seven and forming negatively charged hydroxide ions in water.
- The neutralization reaction between sodium hydroxide and hydrochloric acid produces table salt and water, demonstrating how acids and bases cancel out each other's corrosive properties by forming harmless compounds.

Bases, Lyes, and Neutralization in Chemistry
- Bases, like acids, are an extensive field in chemistry, with a key distinction being that bases are pure substances, such as sodium hydroxide (NaOH), while lyes are aqueous solutions of these substances, like caustic soda.
- Bases and lyes have a pH value greater than seven, indicating alkalinity, and when dissolved in water, bases form OH− ions, which are negatively charged hydroxide ions.
- Sodium hydroxide (NaOH) is a significant base used in laboratories and everyday life, found in drain cleaners due to its corrosive nature, while milder alkaline solutions like soaps and detergents are commonly used.
- When acids and bases are combined in water, they neutralize each other by producing water (H₂O), transforming corrosive substances into harmless ones.
- The chemical reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl) results in the formation of table salt (NaCl) and water (H₂O), showcasing the neutralization process between acids and bases.
