In industry, calcium oxide is reacted with sulfur dioxide to reduce the volume of sulfur dioxide released into the atmosphere.
Explain why calcium oxide is able to reduce the volume of sulfur dioxide released
calcium oxide is base, so forms an alkaline solution when dissolved in water
It will neutralise the sulfur dioxide
Explain the change in the pH of the solution as sulfur dioxide dissolves
pH of solution decreases below 7 because the H+ ion concentration goes up
