The limit test for arsenic is a qualitative test used to determine if the concentration of arsenic in a sample is below a predefined limit. The test is based on the reduction of arsenic (As) to arsine gas (AsH₃), which reacts with silver nitrate to form a yellow to brown stain on filter paper. Chemical … Read more
The limit test for iron is a qualitative test that checks whether the iron ion (Fe³⁺) concentration in a sample is below a specified limit. It is based on a colorimetric reaction between iron ions (Fe³⁺) and potassium thiocyanate (KSCN), forming a red-colored complex. Chemical Reaction: Fe3+(aq) + 6SCN−(aq) → [Fe(SCN)6]3−(aq) Procedure of Limit test … Read more
The limit test for sulfate is a qualitative test that detects whether the sulfate ion (SO₄²⁻) concentration in a sample is below a predefined acceptable limit. It is based on the precipitation reaction between barium ions (Ba²⁺) and sulfate ions (SO₄²⁻), forming an insoluble white precipitate of barium sulfate (BaSO₄). Chemical Reaction: Ba2+(aq) + SO₄2−(aq) … Read more
The limit test for chloride is a qualitative test that detects whether the concentration of chloride ions (Cl⁻) in a sample is below a predefined acceptable limit. It is based on the principle of a precipitation reaction between silver ions (Ag⁺) and chloride ions (Cl⁻), resulting in the formation of an insoluble white precipitate of … Read more
A limit test is a type of analytical method used to determine whether a specific impurity or substance in a pharmaceutical product is present at a concentration below a predefined acceptable limit. Limit tests are typically employed when the impurity or substance is not expected to be present in significant amounts, or when the impurity … Read more
Impurities in pharmaceutical substances are unwanted chemicals or compounds in pharmaceutical substances that can affect the drug’s quality, safety, and efficacy. They are classified into organic, inorganic, or residual solvent impurities and can originate from various sources. Sources of Impurities in pharmaceutical substances 1) Starting Materials and Reagents: Impurities may arise from impure raw materials, … Read more
A pharmacopoeia is an authoritative collection of standards and guidelines for the quality, purity, and strength of drugs, excipients, and dosage forms. It outlines the composition, preparation, storage, and labelling requirements of pharmaceutical products, serving as a reference for healthcare professionals. History of Pharmacopoeia 1) Early Compilations: Early examples include “De Materia Medica” by Dioscorides … Read more
The Joint movements allowed by synovial joints can be classified into several categories: Gliding, Angular, Rotational & Special Movements 1) Gliding Movements Simple sliding motion between flat bone surfaces. Example: Intercarpal joints in the wrist. 2) Angular Joint Movements Types: Flexion: Decreasing the angle between two bones. Example: Bending the elbow. Extension: Increasing the angle between … Read more
Functional classification of joints is based on the degree of movement allowed by the joint. There are three primary functional classification of joints: 1) Synarthrosis (Immovable Joints) These joints allow little or no movement. Example: Sutures of the skull. 2) Amphiarthrosis (Slightly Movable Joints) These joints permit limited movement. Example: The pubic symphysis and intervertebral … Read more
The structural classification of joints is based on the material that binds the bones together and whether or not a joint cavity is present. There are three primary structural classification of joints: 1) Fibrous Joints These joints are connected by dense connective tissue, primarily composed of collagen. They do not have a joint cavity. Types: … Read more
