What Is Produced When Metal Oxides React With Water?
1/4/2020· When metal oxides are put into contact with water, they often, though not always, form metal hydroxides. The reaction depends on the element, the acidity of the metal oxide and on the physical state of the water.
calcium | Definition, Properties, & Compounds | Britannica
The metal reacts slowly with oxygen, water vapour, and nitrogen of the air to form a yellow coating of the oxide, hydroxide, and nitride. It burns in air or pure oxygen to form the oxide and reacts rapidly with warm water (and more slowly with cold water) to produce hydrogen gas and calcium hydroxide.

abiotic factor – a nonliving part of a ecosystem. absolute zero – the lowest temperature that can possibly be reached in our Universe. Scientists have gotten very close to reaching absolute zero but it is impossible to reach it. acid – a sour tasting, corrosive substance – the opposite of a base substance.
Reaction of Aluminum with Water to Produce Hydrogen
Although the concept of reacting aluminum metal with water to produce hydrogen is not new, there have been a nuer of recent claims that such aluminum-water reactions might be employed to power fuel cell devices for portable appliions such as emergency generators and
1 - Making Hydrogen from Metals - IGCSE Chemistry
Any metal that reacts quickly with water is likely to react dangerously violently with acids. Most of them would explode on contact with even dilute Hydrochloric acid. Aluminium is a little less reactive, and takes a while to start reacting because it is covered with a layer of Aluminium Oxide that protects the pure metal from the acid briefly.
