1. Did the given metals react with water? How did you say so?
A common characteristic of most Alkali metals is their ability to displace H2(g) from water. This is represented by their large, negative electrode potentials.
2.Why do you think the metals react with water?
Metals react with water and produce a metal oxide and hydrogen gas. Metal oxides that are soluble in water dissolve in it to further form metal hydroxide. ... Calcium starts floating because the bubbles of hydrogen gas formed stick to the surface of the metal. Magnesium does not react with cold water.
