Definition of Neutralisation Neutralisation Reaction: Neutralisation occurs when an acid reacts with a base to form salt and water, cancelling out their properties. Neutralisation Reaction: Neutralisation is a special kind of chemical process that happens when an acid and a base are mixed together. When they meet, the acid and base cancel out each other’s … Read more

Salts: Definition and Formation Definition of Salts: Salts are compounds formed when hydrogen ions from an acid are replaced by metal or ammonium ions from a base during neutralisation. Definition of Salts: Salts are special types of chemical compounds that are created when hydrogen ions (H⁺) from an acid are replaced by metal ions or … Read more

Preparation of Soluble Salts General Preparation: Soluble salts are produced through reactions resulting in a salt that dissolves in water. General Preparation: Soluble salts are made by carrying out chemical reactions that produce a salt able to dissolve easily in water. This means that after the reaction, the salt will mix with water to form … Read more

Concentration of Aqueous Solutions Definition of Concentration: Concentration describes the amount of solute dissolved in a specified amount of solution. Definition of Concentration: Concentration refers to how much solute (the substance being dissolved) is present in a certain amount of solution. It tells us how “strong” or “weak” a solution is depending on how much … Read more

pH Scale Purpose of pH Scale: The pH scale is designed to measure the acidity or alkalinity of an aqueous solution. Purpose of pH Scale: The pH scale is a tool that scientists and chemists use to measure how acidic or alkaline (basic) a solution that contains water (an aqueous solution) is. It gives a … Read more

Ionisation in Water Ionisation Process: Acids and alkalis dissolve in water and split into positive and negative ions, a process called ionisation. Ionisation Process: When acids and alkalis dissolve in water, they undergo a special change called ionisation. In this process, the substances break apart into two types of charged particles: positive ions and negative … Read more

Chemical Properties of Acids Presence of Hydrogen Ions: Acids exhibit their chemical properties mainly due to hydrogen ions (H⁺) in solution. Presence of Hydrogen Ions: Acids behave the way they do mainly because when they dissolve in water, they release tiny charged particles called hydrogen ions (H⁺). These ions are very active and are the … Read more

Definition and Location What is a Metallic Bond? A metallic bond is a chemical bond found in metals, involving a lattice of positive ions surrounded by free-moving electrons. What is a Metallic Bond?: A metallic bond is a special type of bond found only in metals. In this bond, the atoms don’t just connect in … Read more

Ionic Compounds Electrical Conductivity: Ionic compounds conduct electricity in molten or aqueous form because their ions are free to move and carry electric charge. Electrical Conductivity: Ionic compounds can conduct electricity, but only when they are melted into a liquid (molten) or dissolved in water (aqueous solution). This is because their ions, which carry electrical … Read more

Acids Definition: Acids are substances that release hydrogen ions (H⁺) when dissolved in water. Definition: Acids are special types of substances that, when mixed with water, release hydrogen ions (H⁺). These hydrogen ions are what give acids their sour taste and chemical strength. Ionisation in Water: Acids ionise in water by breaking their covalent bonds, … Read more
