CSEC Chemistry · January 2011 · Paper 2 · Question 5(a)(iii)

Sulphuric acid is prepared industrially via the Contact Process represented in Figure 5.

When sulphur trioxide gets into the atmosphere, it can form acid rain which can destroy buildings made from limestone. Write an ionic equation which BEST represents the chemical reaction taking place when acid rain reacts with limestone.

This question uses a figure or table from the paper — you'll see it when you practise.
