Assignment 7 Power Station Emission
Aim: The aim of this experiment is to measure the mass of sulphur dioxide in 1m3 of flue gas (waste gas from burning fossil fuels in a power station). To achieve this aim, titration of an unknown solution of sulphuric acid (around 0.2-0.4 mol) and sodium carbonate (0.2 mol) using methyl orange as an indicator.
1. Introduction
Fossil fuel is formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years. “As the mud sediment was buried by more sediment, it started to change into

2. Calculations
Sodium carbonate-
C: 0.2 mol dm-3
V: 25cm3

1. Concertation of sodium carbonate:
Number of moles = Volume x concentration 1000

Moles of sodium carbonate = 25 cm3 x 0.2 mol dm-3 = 1000

Moles of sodium carbonate = 0.005 mol dm-3

2. Concentration of sulphuric acid: In this equation, has you can see that the equation is in 1:1 ratio. This means that the number of moles of sodium carbonate at the end-point of the titration is the same as the number of moles of sulphuric acid.

Number of moles of sulphuric acid = Average volume titrated (cm3) x concentration of sulphuric acid (mol dm-3) 1000

This is what it looks like when the equation is
