The addition of calcium hydroxide to soil reduces its acidity but also reduces the efficiency of fertilisers. Which two equations explain this? 1   Ca(OH)   2 (s) + CO 2 (g)   →   CaCO 3 (s) + H 2 O(l) 2   Ca(OH)   2 (s) + 2H + (aq)   →   Ca   2+ (aq) + 2H 2 O(l) 3   Ca(OH)   2 (s) + 2NH 4 NO 3 (aq)   →   Ca(NO 3 )   2 (aq) + 2NH 3 (g) + 2H 2 O(l) 4   Ca(OH)   2 (s) + Cu   2+ (aq)   →   Cu(OH) 2   (s) + Ca   2+ (aq)  A   1 and 2   B   1 and 4   C   2 and 3   D   3 and 4
