examples of solutions acids and bases

📚 Quick Study Guide

• 🧪 Acids: Substances that donate protons ($H^+$) or accept electrons. They have a pH less than 7.
• 🍋 Common Acid Examples:
  • 🍋Citric acid (in citrus fruits)
  • 🚗Sulfuric acid (used in car batteries)
  • 💧Hydrochloric acid (in gastric acid in the stomach)
• ⚖️ Bases: Substances that accept protons ($H^+$) or donate electrons. They have a pH greater than 7.
• 🧼 Common Base Examples:
  • 🧼Sodium hydroxide (in soap and drain cleaner)
  • 🥛Ammonia (in household cleaners)
  • 💊Magnesium hydroxide (in antacids)
• 🔢 pH Scale: A scale used to specify the acidity or basicity of an aqueous solution. It typically ranges from 0 to 14.
• 💡 Neutralization: The reaction between an acid and a base, which results in a salt and water. $Acid + Base \rightarrow Salt + Water$
