Why concentrated hydrochloric acid is not used to prepare hydrogen gas in laboratory?

Concentrated hydrochloric acid (HCl) is not typically used to prepare hydrogen gas in the laboratory because it can react violently with some metals, leading to the release of hazardous hydrogen gas and potentially causing explosions. Dilute hydrochloric acid is safer to use for this purpose as it produces hydrogen gas more slowly and can be better controlled.


Why is copper not used to prepare hydrogen by the action of dilute HCL on metal?

Copper is not suitable for preparing hydrogen by the action of dilute HCl because it is less reactive than hydrogen. In a displacement reaction, hydrogen will not be displaced from hydrochloric acid by copper due to its lower reactivity. Other metals that are more reactive than hydrogen, such as zinc or magnesium, are typically used instead.


How is hydrogen gas prepared in the laboratory?

Hydrogen gas can be prepared in the laboratory through the reaction of a metal (such as zinc or aluminum) with an acid (such as hydrochloric acid). The metal reacts with the acid to produce hydrogen gas as one of the products. This method is safe and commonly used for producing hydrogen gas on a small scale in the laboratory.


Why copper cannot be used to produce hydrogen with hydrochloride?

Oh, honey, let me break it down for you. Copper and hydrochloric acid have a little love-hate relationship - they react together, but not in the way you want for making hydrogen. The copper would just get cozy with the acid and form copper chloride instead of giving you that sweet hydrogen gas. So, if you're looking to get your hands on some hydrogen, you better find a more compatible partner for your copper.


Is copper sulphate alkali?

NO, because copper sulphate doesn't contain hydroxide ions, which is responsible for basic nature.

Can copper be used to prepare hydrogen by reaction with diluteacids?

No. Copper is below hydrogen in the electromotive series and therefore can not displace hydrogen from its compounds.


Can copper be used be to prepare hydrogen by reaction with dilute acids?

No, this would not be a good way. Copper is very unreactive towards dilute acids.


Why is the reaction between potassium and dilute acids not used to prepare hydrogen in the laboratory?

Because they have a more efficient way of doing it.

Why is pure zinc not used to prepare hydrogen gas?

Pure zinc is not used to prepare hydrogen gas because it does not react with water to produce hydrogen gas. Instead, zinc reacts with acids like hydrochloric acid to form zinc chloride and release hydrogen gas. This reaction is utilized in the laboratory to produce hydrogen gas.


What is copper 2 hydrogen carbonate?

Copper(II) hydrogen carbonate is a chemical compound with the formula Cu(HCO3)2. It is a blue-green solid that is not stable and decomposes easily. It is used in some laboratory and industrial processes, but it is not commonly encountered in everyday life.

Is copper wire a substance?

Copper used in wiring would not qualify as laboratory-grade (pure). It would be too expensive to manufacture.


What type of gases are used to prepare Ammonia gas?

Nitrogen and hydrogen


Why does sulphuric acid have to be warm to be used in the copper oxide reaction?

Because copper isn't reactive enough to displace hydrogen if the solution is cool or cold. It becomes easier for copper to replace the hydrogen when the solution is warm.


Why don't we make hydrogen when reacting an acid with copper?

Copper is unreactive and will not react with acids to liberate hydrogen gas. However it may react if concentrated and oxidising acids are used.
