Welcome back WELZIE — missed you this week. Here are notes on Acids and Bases for Grade 12: Acids are substances that donate protons (H⁺ ions) in aqueous solution. They typically have a sour taste and can corrode metals. Properties: Sour taste Turn blue litmus paper red React with active metals to produce hydrogen gas (H₂) React with bases in a neutralization reaction to form salt and water Conduct electricity in solution Examples: Hydrochloric acid (HCl), Sulfuric acid (H₂SO₄), Nitric acid (HNO₃) Bases are substances that accept protons (H⁺ ions) or donate hydroxide ions (OH⁻) in aqueous solution. They often have a bitter taste and feel slippery. Properties: Bitter taste Feel slippery to the touch Turn red litmus paper blue React with acids in a neutralization reaction to form salt and water Conduct electricity in solution Examples: Sodium hydroxide (NaOH), Potassium hydroxide (KOH), Calcium hydroxide (Ca(OH)₂) pH Scale: The pH scale measures the acidity or alkalinity of a solution. It ranges from 0 to 14. pH < 7: Acidic* solution (higher concentration of H⁺ ions) pH = 7: Neutral* solution (equal concentration of H⁺ and OH⁻ ions) pH > 7: Alkaline or Basic* solution (higher concentration of OH⁻ ions) Neutralization Reaction: This is a reaction between an acid and a base, producing a salt and water. General form: Acid + Base → Salt + Water Example: HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l) Send me the next one 📸
