Key Topics to Revise

1

Fundamentals of Analytical Chemistry

  • Analytical chemistry facilitates investigation of chemical composition using instruments and methods to separate, identify, and quantify matter
  • Two main types: Qualitative analysis (detection of presence/absence of elements) and Quantitative analysis (determination of relative proportions)
  • Applications in forensic science, medicine, agriculture, industry, and environmental monitoring
2

Scientific Notation and Mathematical Operations

  • Scientific notation expresses very large or small numbers as N × 10ⁿ where 1 ≤ N < 10
  • Addition/Subtraction: Make exponents equal, then add/subtract coefficients
  • Multiplication: Multiply coefficients, add exponents
3

Precision, Accuracy, and Error Analysis

  • Accuracy: Nearness of measured value to true value
  • Precision: Reproducibility of measurements (consistency)
  • High precision is prerequisite for high accuracy
4

Significant Figures

  • Significant figures represent certainty in measurements plus one uncertain digit
  • Rules: (1) All non-zero digits significant, (2) Zeros between non-zeros significant, (3) Leading zeros not significant, (4) Trailing zeros significant if decimal present
  • In calculations, result limited by least precise measurement
