Study Notes
Strong Acids
- Strong acids fully dissociate in water, releasing hydrogen ions (H+).
- Hydrochloric acid (HCl) and nitric acid (HNO3) are considered strong acids.
- Hydrobromic acid (HBr) is also a strong acid.
- Hydroiodic acid (HI) and sulfuric acid (H2SO4) are strong acids as well.
- Perchloric acid (HClO4) is categorized as a strong acid.
Strong Bases
- Strong bases fully dissociate in water, producing hydroxide ions (OH-).
- Sodium hydroxide (NaOH), potassium hydroxide (KOH), and barium hydroxide (Ba(OH)2) are classified as strong bases.
- Calcium hydroxide (Ca(OH)2) is recognized as a strong base.
- Strontium hydroxide (Sr(OH)2) is also a strong base.
Summary of Strong Acids and Bases
- Strong acids: HCl, HNO3, HBr, HI, H2SO4, HClO4.
- Strong bases: NaOH, KOH, Ba(OH)2, Ca(OH)2, Sr(OH)2.
