# Problem with synthesis of calcium formate

I just tried preparing calcium formate by adding $$\ce{Ca(OH)2}$$ to ammonium formate, but I observed no bubble formation and no smell of ammonia. Why doesn't calcium hydroxide, being a strong base, displace ammonia?

• There is a multitude of possibilities. For one thing, Ca(OH)2 isn't that strong a base. For another, maybe it does displace ammonia, but the solution is too dilute to detect the smell, let alone the bubbles. NH3 never forms bubbles. – Ivan Neretin Dec 23 '19 at 15:21
• Did you check the solubilities of calcium formate,16.1 g/100 g (0 °C), and calcium hydroxide, 0.173 g/ 100 ml (20 °C)? – MaxW Dec 23 '19 at 17:48
