Which metal is displaced by metal from acid?
Answer: Active metals can displace hydrogen ions from acids due to their high reactivity.
Which metals can liberate hydrogen from acids?
Since Na Fe and Pb occur above hydrogen in the activity series they will liberate hydrogen from dilute acids.
Can Zn displace h2 from acid?
Zinc can easily displace hydrogen from dilute Sulphuric acid but copper cannot.
Which metals react with acids to form hydrogen?
Summary. Magnesium, mossy zinc and copper foil are reacted with hydrochloric acid to produce hydrogen gas and a salt.
Which metals can displace hydrogen from acid?
Hence, Sodium and Potassium are two metals that can displace hydrogen from dilute acids to form metal salts and hydrogen gas.
Can silver displace hydrogen from acid?
Hence, the two metals which are unable to displace Hydrogen are Copper and Silver.
Why can’t copper liberate H2 from acid?
Copper is less active than Hydrogen and so it cannot replace it from acids and so it cannot liberate hydrogen with dilute acids.
Which metal gives off hydrogen?
Metals which are more reactive than hydrogen in the reactivity series can react with acid and produce hydrogen gas. Such metals are:—potassium, sodium, calcium, magnesium, aluminium, zinc, iron etc.
Can lead displace hydrogen?
Lead (Pb) – Lead is above hydrogen in the reactivity series. It means that lead can displace hydrogen from acids. So, when lead reacts with hydrochloric acid, it displaces the hydrogen, creating a salt (lead chloride, PbCl2) and liberating hydrogen gas.
Can copper displace H2 from acid?
Copper has positive electrode potential; hence it cannot displace hydrogen from dilute acids.
What displaces hydrogen?
Na and K are highly reactive active metals and are present on top of activity series so they can displace hydrogen by reaction with water.
Can nickel displace hydrogen in an acid?
Answer and Explanation: Nickel lies above hydrogen in the reactivity series while silver and copper lies below hydrogen. So only nickel is more reactive than hydrogen and thus can displace hydrogen in an acid.
Which metals does not give hydrogen with acid?
Copper does not show any reaction with acids so hydrogen gas is not evolved.
Why don’t all metals react with acid?
Some metals react with acids due to their position in the reactivity series, while others don’t due to their lower reactivity. The reactivity of metals with acids is primarily determined by their position in the reactivity series. The reactivity series is a list of metals ranked in order of decreasing reactivity.

Which Metals Will Displace Hydrogen From an Acid?
You might be wondering, “What’s the big deal about a metal displacing hydrogen?” Well, it’s actually a pretty fundamental concept in chemistry, and it’s all about the activity series of metals.
The activity series is a list of metals arranged in order of their reactivity, with the most reactive metal at the top. This reactivity determines whether a metal can displace hydrogen from an acid or not.
The Activity Series
Here’s a simplified version of the activity series:
| Metal | Reactivity |
|—|—|
| Potassium (K) | Very reactive |
| Sodium (Na) | Very reactive |
| Calcium (Ca) | Reactive |
| Magnesium (Mg) | Reactive |
| Aluminum (Al) | Reactive |
| Zinc (Zn) | Reactive |
| Iron (Fe) | Moderately reactive |
| Lead (Pb) | Moderately reactive |
| Hydrogen (H) | |
| Copper (Cu) | Less reactive |
| Silver (Ag) | Less reactive |
| Gold (Au) | Least reactive |
So, what’s the deal with this list? Metals that are higher in the activity series are more likely to displace hydrogen from an acid.
The Displacement Reaction
Let’s break down what happens when a metal displaces hydrogen from an acid. The key is a single displacement reaction.
Think of it like this:
Metal + Acid → Salt + Hydrogen Gas
Here’s a classic example:
Zinc (Zn) + Hydrochloric Acid (HCl) → Zinc Chloride (ZnCl₂) + Hydrogen Gas (H₂)
In this reaction:
Zinc is more reactive than hydrogen, so it takes the place of hydrogen in the acid.
Zinc chloride is formed as a salt.
Hydrogen gas is released as bubbles.
Rules of the Road
Now, let’s lay down the rules:
1. Metals above Hydrogen in the activity series will displace hydrogen from acids.
2. Metals below Hydrogen in the activity series won’t displace hydrogen from acids.
3. The reactivity of the metal determines how readily it displaces hydrogen.
Examples
Potassium (K), being highly reactive, will readily displace hydrogen from even weak acids like acetic acid (CH₃COOH).
Magnesium (Mg), being less reactive than potassium, will displace hydrogen from hydrochloric acid (HCl) but may not react with acetic acid.
Copper (Cu), being less reactive than hydrogen, won’t displace hydrogen from any acid.
Factors Influencing Displacement
While the activity series is a great starting point, it’s not the whole story. Here are a few things to keep in mind:
Concentration of the acid: A more concentrated acid will react more vigorously.
Temperature: Raising the temperature generally speeds up the reaction.
Surface area of the metal: A larger surface area allows for more contact with the acid, leading to a faster reaction.
Real-World Applications
This concept of metal displacement is crucial in many areas, including:
Production of hydrogen gas: The reaction between metals like zinc and acids is used to generate hydrogen gas for various industrial processes.
Corrosion: Metals react with acids in the environment, leading to corrosion.
Electrochemistry: Understanding the reactivity of metals is essential in batteries and other electrochemical devices.
FAQs
Q: Can all metals displace hydrogen from acids?
A: No, only metals that are more reactive than hydrogen can displace it from acids. This is determined by the activity series of metals.
Q: What happens if the metal is less reactive than hydrogen?
A: If the metal is less reactive than hydrogen, no reaction will occur. The metal won’t displace hydrogen from the acid.
Q: How can I determine if a metal will displace hydrogen from an acid?
A: You can use the activity series of metals. If the metal is higher in the activity series than hydrogen, it will displace hydrogen from an acid.
Q: Is there a way to predict the rate of reaction?
A: The rate of reaction depends on several factors, including the concentration of the acid, the temperature, and the surface area of the metal. You can generally predict that more reactive metals will react faster and that higher concentrations, temperatures, and surface areas will result in faster reactions.
Q: What are some real-world examples of metal displacement reactions?
A: Metal displacement reactions are used in the production of hydrogen gas, the corrosion of metals, and the operation of electrochemical devices like batteries. For example, zinc reacts with hydrochloric acid to produce hydrogen gas, which can be used as a fuel or in industrial processes. Iron reacts with oxygen and water to form rust, a form of corrosion.
Q: Can I perform these reactions at home?
A: While it’s exciting to experiment with chemistry, it’s best to leave metal displacement reactions to a lab setting. Some of these reactions can produce flammable hydrogen gas, and working with acids requires caution.
I hope this breakdown of metal displacement helps you understand the basics. Now you can predict which metals will kick hydrogen out of an acid and how these reactions work! Remember, the world of chemistry is filled with fascinating reactions and endless possibilities!
