Water turned pink in a small Canadian town this week after a faulty valve allowed the disinfectant potassium permanganate to seep into the water supply. The color looks alarming, but the chemical ...

How does a chemical reaction proceed at ultralow temperatures? Can simple quantum mechanical rules such as quantum statistics, single partial-wave scattering, and quantum threshold laws provide a ...

The apparatus below is used to react calcium with water and collect the gas. This would not be used with sodium or potassium as they float and the reaction is too vigorous.
