Smog, Acid Rain, Aqi — Smog Types
Grey coal smog vs brown photochemical. PAN irritates eyes (named). Temperature inversion named as trapping pollution (weather idea). Acid rain: H2SO4 and HNO3 from SO2 and NO2 — damages buildings and lakes. This page separates the idea from the wider topic “SMOG, ACID RAIN, AQI” so it can be revised and assessed on its own.

In simple words
- Grey coal smog vs brown photochemical.
- Coal + SO2
- Exam link: named types.
Important terms
SMOG TYPES: Grey coal smog vs brown photochemical.
SMOG, ACID RAIN, AQI: Classical smog: smoke + fog + SO2 (old coal cities named).
What you should learn
- Define smog types using accurate chemistry terms.
- Explain why smog types matters within smog, acid rain, aqi.
- Apply the learning unit to an FBISE-style example, comparison, diagram, or calculation.

WHY — Why this topic matters
SMOG, ACID RAIN, AQI — SMOG TYPES is an independent FBISE learning unit because students must use its definitions, conditions, equations, or trends separately in explanations and calculations.
HOW — How it works
Grey coal smog vs brown photochemical. PAN irritates eyes (named). Temperature inversion named as trapping pollution (weather idea). Acid rain: H2SO4 and HNO3 from SO2 and NO2 — damages buildings and lakes. Examples: Coal + SO2; Sun + NOx; Inversion named. Exam use: Exam photochemical smog: sunlight + NOx + hydrocarbons ground ozone and PAN named prevention: fewer vehicle emissions (slogan)

Common exam traps
- Do not treat smog types as the same as every other part of smog, acid rain, aqi; define this unit and use its own evidence, steps, or conditions.
- Do not memorise a label alone; connect the definition to a process, structure, condition, equation, or example.
