Aluminum is a silvery metal that will evolve hydrogen gas when reacted with a strong acid. Aluminum will also evolve hydrogen gas as a product of its reaction with a strong acid.

How has hydrogen gas been made through chemical reactions?
strong acids like sulphuric acid reacted with metals like zincwater reacted with alkali metalselectrolysisetc.
Why hydrogen is not evolved when a metal react with nitric acid?
Nitric acid is a strong oxidizing agent and its molecule is unstable as compare to nitrogen oxides, on reacting with metals it gives hydrogen and oxygen both so water is produced instead of hydrogen.
What is product when hydrogen abd oxygen react?
Given the energetics presented above, there is a strong thermochemical bias for the production of water over hydrogen peroxide when H2 and O2 are reacted together.
Why are you not allowed to use all alkali metals?
They are highly reactive. For example, the reaction of potassium with water is highly vigorous and the hydrogen gas evolved would catch fire. Also, the hydroxide produced is very corrosive because it is a strong alkali.
What reacts with a metal what gas produced?
Many metals react with strong acids to produce hydrogen gas.
When was hydrogen discovered?
Hydrogen, H2, was first generated and described by Paracelsus, who was T. Von Hohenheim (1493 to 1541). He reacted strong acids with metals to produce it. Credit for the discovery of hydrogen is usually ascribed to Henry Cavendish, who produced it, discovered it burned and produced water upon combustion, and also proposed it was a unique element, which he did in 1776. A link can be found below.
What metals are strong in room temperature?
Metals like steel are strong in room temperature. If you want anymore, search for metals as strong as steel :)
What is the cheapest metal for making hydrogen?
Iron reacted with a strong acid would probably be cheapest, but aluminum reacted with sodium hydroxide solution is commonly used when hydrogen needs to be produced at remote sites like for weather balloons. Iron only reacts slowly with acid but the reaction between aluminum and sodium hydroxide is very rapid (and dangerous if it is not carefully controlled) producing large quantities of hydrogen. 1 mole of Aluminium will produce 1.5 moles of hydrogen gas or about 1 liter of hydrogen gas for every gram of aluminum.
Why nitric acid does not liberate hydrogen gas with most metals?
It is because HNO3 is a strong oxidising agent.So as soon as H2 is formed in the reaction between a metal and dilute nitric acid oxidises this hydrogen to water.
Is a hydrogen a very strong dipole-dipole force?
The hydrogen bond is not strong.
Is the hydrogen bonding in hydrogen bromide strong or weak?
It's a strong bond.
What hydrogen bromide acid or strong base?
Hydrogen bromide is a strong acid.
