Do Bases React With Metals To Produce Hydrogen Gas
Alkali reacts with metal to generate hydrogen. In the world of alkali and metal, it is often doubted whether it can generate hydrogen. Those with alkali, with hydroxide and the like, and those with metal, are mostly active or more active things.
Looking at the common bases, such as sodium hydroxide and potassium hydroxide, although their properties are strong, they can not all produce hydrogen when they meet with metals. At room temperature, common metals such as iron and copper are mixed with alkali, and there is no smell of hydrogen escaping. This cover is due to the insufficient activity of iron and copper, and it is difficult to react violently with alkali to capture the hydrogen of hydroxide in alkali.
However, there are exceptions. Such as the genus of aluminum, it is sexually active and bisexual. When aluminum encounters a strong alkali, such as sodium hydroxide solution, it undergoes a wonderful change. Aluminum reacts with sodium hydroxide and water to produce sodium aluminate and hydrogen. The reaction formula is as follows: $2Al + 2NaOH + 2H_ {2} O = 2NaAlO_ {2} + 3H_ {2}\ uparrow $. In this case, aluminum reacts with water first to produce aluminum hydroxide and hydrogen, and then aluminum hydroxide reacts with sodium hydroxide to form sodium aluminate, so in general, hydrogen escapes.
If there is zinc, it can also respond to strong bases. Under suitable conditions, the reaction of zinc and alkali can also produce hydrogen. The reactivity of zinc cap is suitable, and it can interact with the components in the alkali solution to release hydrogen and turn it into hydrogen.
In summary, the reaction between alkali and metal does not generate hydrogen uniformly. Metals with suitable reactivity and specific properties have the possibility of generating hydrogen when encountering strong alkalis, while most common metals do not generate hydrogen with alkalis under normal conditions. Therefore, when considering this matter, when carefully examining the properties of metals and the quality of alkalis, it cannot be generalized.
