1. General Information and Introduction 2. Laboratory Preparation Nitric acid is prepared in the lab by heating potassium nitrate (KNO3) or sodium nitrate (NaNO3) with concentrated sulfuric acid (H2SO4). The reaction is carried out in an all-glass apparatus because the vapors of nitric acid are highly corrosive and would attack rubber or cork. KNO3+H2SO4<200°CKHSO4+HNO3 The…
1. General Information and Introduction 2. Industrial Manufacturing: The Contact Process The Contact Process is the main industrial method for producing sulfuric acid. It involves three key steps: 3. Chemical Properties As an Acid: As a Non-Volatile Acid: As an Oxidizing Agent: As a Dehydrating Agent: 4. Uses of Sulfuric Acid Sulfuric acid is often…
General Information and Introduction 2. Laboratory Preparation of Hydrogen Chloride Gas 3. The Fountain Experiment This is a classic experiment used to demonstrate two key properties of HCl gas: 4. Preparation of Hydrochloric Acid Hydrochloric acid is prepared by dissolving HCl gas in water. A special funnel arrangement is used to prevent back-suction (water rushing…
Chapter: Acids, Bases, and Salts Introduction Acids, bases, and salts are fundamental concepts in chemistry that play crucial roles in various chemical reactions and our daily lives. Understanding their properties and reactions is essential for comprehending many natural and industrial processes. Acids Definition and Properties Types of Acids Bases Definition and Properties Types of Bases…
The periodic table is a fundamental tool in chemistry that helps understand the physical and chemical properties of elements. These properties follow specific trends due to the arrangement of elements based on their atomic number and electronic configuration. The concept of periodicity arises because elements with similar outer electron configurations exhibit similar characteristics at regular…
Calcium Chloride reacts with sodium hydroxide to form a white precipitation of calcium hydroxide and sodium chloride. Calcium hydroxide is insoluble in excess NaOH.
Calcium nitrate reacts with sodium hydroxide to form a white precipitation of calcium hydroxide and sodium nitrate. Calcium hydroxide is insoluble in excess NaOH.

Which gas Decolourises potassium permanganate (KMnO4) solution? (a) Sulphur dioxide(b) Ammonia(c) Hydrogen chloride(d) Carbon dioxide Ans: Sulphur dioxide The Chemistry Behind the Decolorization Potassium permanganate (KMnO₄) is a strong oxidizing agent, meaning it readily accepts electrons. In its usual state, the permanganate ion (MnO₄⁻) imparts a deep purple color to the solution. Sulphur dioxide (SO₂)…
