# Chemistry Formula Sheet This document appears to be notes on acids and bases. It includes various topics related to these concepts, including formulas, examples, and definitions. **Strong Acids:** * HCl: Hydrochloric acid * HNO₃: Nitric acid * H₂SO₄: Sulphuric acid * H₃PO₄: Phosphoric acid * HF: Hydrofluoric acid **Weak Acids:** * CH₃COOH: Ethanoic acid * H₂CO₃: Carbonic acid **Calculations for Masses:** The document mentions calculating masses using Molar Mass, Avogadro's number, and other chemical concepts. **pH Scale and Indicators:** * A diagram showing a triangle representing a PH scale is present. * The document also describes how different indicators (e.g., Universal Indicator, Litmus paper, phenolphthalein) change color depending on whether the substance is an acid, base, or neutral. It relates color changes to the pH value. **Definitions of Acids and Bases:** * **Acid**: An acid releases hydrogen ions (H⁺) when dissolved in water. It's a proton donor. * **Base**: A base releases hydroxide ions (OH⁻) when dissolved in water. It's a proton acceptor There are a number of related chemical formulas and associated details like molar mass, molecular weight in grams, and other details are present in the document.
