Answer (1)
Answer:Let's break down the assignment:Question 1: Differentiate between acids and basesYou need to compare and contrast these two chemical substances based on: * Taste: Acids usually taste sour, while bases taste bitter. * Solubility in water: Many acids and bases are soluble in water. * Litmus paper color: Acids turn blue litmus paper red, while bases turn red litmus paper blue.Examples: * Acids: Lemon juice, vinegar, hydrochloric acid * Bases: Baking soda, ammonia, sodium hydroxideQuestion 2: Explain why: * a. An antacid tablet is prescribed when you suffer from acidity: Antacids contain bases that neutralize excess stomach acid, providing relief from heartburn or indigestion. * b. Calamine solution is applied on the skin when an ant bites: Calamine lotion contains zinc oxide and often phenol, which have soothing and anti-itch properties to counteract the acidic venom injected by an ant bite. * c. Factory waste is neutralized before disposing it into the water bodies: Neutralizing factory waste helps prevent water pollution by reducing the acidity or alkalinity of harmful substances, which can harm aquatic life and ecosystems.
