Measurement of concentration | physical methods | FSC first year chemistry class 11 chemistry

📘 Measurement of Concentration — Physical Methods | FSc 1st Year Chemistry In this lecture, we will study physical methods for measuring the concentration of a substance in a solution or reaction mixture. These methods are especially useful when the concentration needs to be determined by measuring a physical property of the system. In this FSc 1st Year Chemistry lecture, we discuss: 🔹 Spectrophotometry — determining concentration by measuring how much light is absorbed by a solution. 🔹 Electrical Conductivity Method — determining concentration by measuring the electrical conductivity of a solution, which depends on the ions present. 🔹 Volume Change Method (Gas Syringe Method) — determining concentration by measuring the change in volume of a gas produced during a reaction using a gas syringe. These physical methods are important in chemical kinetics because they allow us to monitor changes during a reaction and determine how the concentration changes with time. 🎓 Level: FSc 1st Year Chemistry 📚 Topic: Measurement of Concentration — Physical Methods 🧪 Methods Covered: Spectrophotometry, Electrical Conductivity & Gas Syringe Method Explore Chemistry with Awais — Learn chemistry with clear concepts, simple explanations, and practical examples. #FScChemistry #1stYearChemistry #ChemicalKinetics #MeasurementOfConcentration #Spectrophotometry #ElectricalConductivity #GasSyringe #ChemistryLectures #ExploreChemistryWithAwais
