2020/6/1· The effects of the chemical reaction between water and aluminium June 01, 2020 12:12 Aluminium power cables can potentially fail due to the following reasons: corrosion, thermal expansion and the reaction of water with aluminium. This article looks at the latter.
Intro 1.4-Lecture Demonstrations-Department of …
Calcium metal is an alkaline earth metal found in Group 2A and reacts with water to form calcium hydroxide and hydrogen gas. Group 2A metals don’t have as high a solubility in water as Group 1A, which is why the reaction of calcium (or magnesium) in water goes faster in warm water and also explains why calcium is found in various minerals.
