\nEffluent from the electroplating industry contains acids such as sulphuric acid and must be treated before it is discharged into rivers and streams. The acids in the effluent are neutralised by adding lime.<\/li>\n
\nPower stations burn coal to produce electricity. Coals contain sulphur and burning sulphur in air produces sulphur dioxide which is responsible for the formation of acid rain.

\nWhen a mixture of coal and limestone is heated, the limestone decomposes to form lime.

\nThe lime neutralises the acidic sulphur dioxide.

\nSulphuric acid plants use the Contact process to produce sulphuric acid. Sulphur dioxide gas is produced from the combustion of sulphur or from the roasting of sulphide ores. To prevent sulphur dioxide gas from escaping into the atmosphere, waste gases are scrubbed by passing through powdered lime. Lime neutralises the acidic sulphur dioxide.
