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
Covalent Bond Basics Definition of Covalent Bond: A covalent bond is formed when atoms share pairs of valence electrons, usually between non-metal atoms. Definition of Covalent Bond: A covalent bond happens when two atoms, usually non-metal atoms, decide to share electrons from their outermost shells. These shared electrons help both atoms feel more stable because … Read more
Definition and Nature What is a Hydrogen Bond? A hydrogen bond is an attractive force occurring when hydrogen is covalently bonded to a highly electronegative atom (F, O, or N) and is attracted to another electronegative atom. What is a Hydrogen Bond?: A hydrogen bond is a special kind of force that pulls molecules together. … Read more
Definition and Nature What is a Dative Bond? A dative bond is a type of covalent bond where both electrons in the shared pair come from the same atom. What is a Dative Bond?: A dative bond is a special kind of covalent bond. Normally, in covalent bonds, two atoms share a pair of electrons, … Read more
