Understanding Acids, Bases, and Salts
What Are Acids?
Acids are substances that release hydrogen ions (H⁺) when dissolved in water. They typically have a sour taste and can react with metals to produce hydrogen gas. Common examples include:
- Hydrochloric acid (HCl)
- Sulfuric acid (H₂SO₄)
- Citric acid
Characteristics of Acids:
- Sour taste
- React with metals to produce H₂ gas
- Turn blue litmus paper red
- Conduct electricity in aqueous solutions
- Corrosive in concentrated forms
What Are Bases?
Bases are substances that release hydroxide ions (OH⁻) in aqueous solutions. They often have a bitter taste and a slippery feel. Examples include:
- Sodium hydroxide (NaOH)
- Potassium hydroxide (KOH)
- Ammonia (NH₃)
Characteristics of Bases:
- Bitter taste
- Slippery or soapy feel
- Turn red litmus paper blue
- Conduct electricity in solutions
- Can neutralize acids to form salts
What Are Salts?
Salts are ionic compounds formed when acids react with bases in a neutralization reaction. They are composed of positive ions (cations) and negative ions (anions). Examples include:
- Sodium chloride (NaCl)
- Potassium sulfate (K₂SO₄)
- Calcium carbonate (CaCO₃)
Features of Salts:
- Crystalline solids
- Usually soluble in water
- Have diverse applications in industry and daily life
