KCET Chemistry Formulas PDF

The KCET Chemistry Formulas are essential for students preparing for the KCET entrance exam, which helps eligible candidates gain admission to various undergraduate programs in Karnataka. Also known as Karnataka CET, Kar CET, KEA UGCET, or K-CET, this examination covers professional courses like B.Tech, B.E, B. Pharm, B.Arch, and BSc.

Eligibility and Exam Overview

To be eligible, candidates must have completed their 2^nd PUC/12^th Standard or an equivalent examination with at least 45% marks in Physics and Mathematics, along with Chemistry/Biology/Biotechnology/Electronics/Computer (40% for reserved categories). The KCET exam consists of four subjects: Physics, Chemistry, Mathematics, and Biology. The 2023 syllabus is aligned with the higher secondary curriculum, and each subject is allotted an exam duration of 80 minutes, featuring 60 questions.

KCET Chemistry Formulas

• Matter: Substance that has mass and takes up space, e.g., water, air, box, table, etc.
• State of Matter: Matter can exist in three states: solid, liquid, and gas. The plasma state, or the fourth state, occurs at very high temperatures with gaseous ions and free electrons.
• Homogeneous: These have a uniform composition throughout, e.g., elements and compounds. Mixtures can also be homogeneous.
• Heterogeneous: These do not have a uniform composition, e.g., a mixture of iron filings and sulfur powder.
• Element: A substance that cannot be divided further by chemical means. Elements can be metals, non-metals, or metalloids, e.g., F, Al, Ni, Au, Ag are metals; C, S, N₂, I₂ are non-metals; and B, Si, As, Sb are metalloids.
• Compound: A pure substance made from two or more elements in a fixed ratio, e.g., NaCl, FeS, CuSO₄, H₂O. These components cannot be separated by physical means.

1. Organic Compounds: Compounds mainly containing carbon along with elements like H, N, S, halogens, phosphorus, and oxygen, e.g., sugar, urea, glucose.
2. Inorganic Compounds: Made from two or more elements from minerals and ores, e.g., NaCl, KCl, CaCO₃.

• Mixture: Consists of two or more elements or compounds in varying ratios that can be separated using physical methods. It can be homogeneous (e.g., salt in water) or heterogeneous (e.g., dust particles in air). Homogeneous mixtures are also called solutions.
• Separation of Mixtures: Mixtures are separated based on the properties of their components, which differ from each other.

1. Filtration: Used to separate insoluble components from a soluble one, where the soluble component passes into the filtrate, and the insoluble residue remains on filter paper. The soluble part can be obtained by evaporation.
2. Simple Distillation: Employed for separating miscible liquids which significantly differ in boiling points, e.g., benzene and toluene.
3. Fractional Distillation: For separating miscible liquids with slight differences in boiling points.

• Molecules: The smallest identifiable units of matter which can be made up of two or more atoms, either of the same or different elements, combined in a definite ratio.
• Atomicity: Refers to the number of atoms present in a molecule.
• Monoatomic: Composed of a single atom, e.g., He, Ne, Ar, Kr, Xe, Na, K.
• Diatomic: Consists of two atoms, e.g., H₂, Br₂, Cl₂, F₂, I₂, N₂, O₂, HCl, HBr.
• Triatomic: Comprises three atoms, e.g., O₃, H₂O, SO₂, CO₂.
• Tetra-atomic: Contains four atoms, e.g., P₄, SO₃, NH₃.
• Penta-atomic: Composed of five atoms, e.g., CH₄, CCl₄, SiCl₄.
• Hexa-atomic: Contains six atoms, e.g., C₂H₄, H₂SO₃.
• Hepta-atomic: Contains seven atoms, e.g., H₂SO₄.
• Octa-atomic: Comprising eight atoms, e.g., S₈ is an example of an octa-atomic molecule.
