Finding out How Much Acid There is in a Solution Planning: - Introduction: - During the extraction of a metal from its ore, sulphur dioxide is often produced. This is converted to sulphuric (VI) acid and is sold as a useful by-product. I am going to be given a sample of sulphuric acid which is thought to have a concentration between 0.05 and 0.15 mol dm3. I have to find out its accurate concentration by carrying out a titration between sulphuric acid and sodium carbonate. It is an acid-alkali titration. A titration is the "determination of material concentration by the successive addition of measured amounts of standard reagents to a known volume or weight of solution until a desired end point is reached." Acids and alkalis are classified as "strong" or "weak" depending on the extent to which they form ions when dissolved in water. Sulphuric acid is a strong acid which means...
