Here is an experiment where sodium reacts with four different acids - 6M HCl, 12M HCl, 6M HNO3 and 15M HNO3.

The reaction with 15M HNO3 is the fastest and 12M HCl is the slowest reaction and it...

Sodium does not react easily with oxygen at a room temperature so it has to be heated up a little for the reaction to start.

Since air is mostly oxygen once the reaction starts it gets pretty...
