Can silver displace hydrogen from acid?
Hence, the two metals which are unable to displace Hydrogen are Copper and Silver.
Why do metals replace hydrogen from acids?
Metals have a tendency to lose electrons and hence they supply electrons i.e. they are electrondonors. That is why metals displace hydrogen from dilute acids. On the other hand non-metal is an electron acceptor. It cannot supply electrons to H+ and hence it does not displace hydrogen from dilute acids.
Can copper displace hydrogen?
Copper has positive electrode potential; hence it cannot displace hydrogen from dilute acids. But a number of other elements in 3d series except displace hydrogen from dilute acids.
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.
Can lithium displace hydrogen from acids?
any element which is higher is the series than H+, will have the ability to displace hydrogen ion from an acid. for examples, zinc metal, lithium, sodium metal, iron.

Which metal can displace hydrogen from water?
Can a metal displace hydrogen?
Can a metal displace H2 from acidic solutions?
You know how sometimes you mix things together and something totally new happens? Well, that’s what happens when you mix certain metals with acids. It’s like a chemical magic trick!
You see, some metals are really good at displacing hydrogen from acids. It’s all about their reactivity – how much they want to react with something else.
Think of it like a tug-of-war. The metal is on one side, and the hydrogen is on the other side, both pulling on the acid. The metal that wins the tug-of-war will displace the hydrogen and create a brand new substance!
So, which metals win this tug-of-war?
Well, let’s dive into the exciting world of metal reactivity and find out!
The Reactivity Series: Your Guide to Metal Mayhem
The reactivity series is our secret weapon. It’s like a list of metals, ranked by how much they love to react. The metals at the top are the most reactive, and they’re the ones who can push hydrogen out of the way.
Here’s the general idea:
Metals higher on the reactivity series are more reactive and can displace hydrogen from acids.
Metals lower on the reactivity series are less reactive and can’t displace hydrogen from acids.
Here’s a simplified version of the reactivity series:
Most Reactive
1. Potassium (K)
2. Sodium (Na)
3. Lithium (Li)
4. Calcium (Ca)
5. Magnesium (Mg)
6. Aluminium (Al)
7. Zinc (Zn)
8. Iron (Fe)
9. Lead (Pb)
10. Hydrogen (H)
11. Copper (Cu)
12. Silver (Ag)
13. Gold (Au)
14. Platinum (Pt)
Least Reactive
Remember: This is a simplified version, and there are other factors that can influence reactivity.
The Great Hydrogen Displacement: How It Happens
Let’s imagine we have zinc (Zn) and hydrochloric acid (HCl).
1. Zinc is higher on the reactivity series than hydrogen.
2. This means zinc is more eager to react than hydrogen.
3. When zinc is added to hydrochloric acid, it displaces the hydrogen.
4. This means the hydrogen leaves the acid and forms hydrogen gas.
The chemical equation looks like this:
Zn + 2HCl → ZnCl2 + H2
Zinc (Zn) reacts with hydrochloric acid (HCl).
Zinc chloride (ZnCl2) is formed, and hydrogen gas (H2) is released.
Metals That Displace Hydrogen From Acids
Now that we understand the basics, let’s focus on the metals that can displace hydrogen from acids:
Group 1 Metals (Alkali Metals): These guys are the superstars of reactivity. They can easily displace hydrogen from acids like hydrochloric acid (HCl) and sulfuric acid (H2SO4). They include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
Group 2 Metals (Alkaline Earth Metals): These metals are also quite reactive. They can displace hydrogen from acids, but not as readily as the alkali metals. These include beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
Aluminium (Al): Aluminium is an interesting case. It forms a protective layer of aluminium oxide (Al2O3) which slows down its reaction with acids. However, if you use a strong acid like hydrochloric acid (HCl), it can still displace hydrogen.
Zinc (Zn), Iron (Fe), and Lead (Pb): These metals are less reactive than the alkali metals and alkaline earth metals, but they can still displace hydrogen from acids.
Metals That Don’t Displace Hydrogen From Acids
Here are the metals that are too shy to displace hydrogen:
Copper (Cu), Silver (Ag), and Gold (Au): These metals are less reactive than hydrogen and won’t displace it from acids. They’re like the introverts of the metal world!
Platinum (Pt): Similar to gold and silver, platinum is a very unreactive metal and won’t displace hydrogen.
It’s Not Just About The Metal!
While the reactivity series is a great guide, it’s not the only factor that determines whether a metal can displace hydrogen. Here’s a bit more detail:
The Concentration of the Acid: A more concentrated acid will have a higher concentration of hydrogen ions, making it more likely that a metal can displace hydrogen.
The Temperature: Increasing the temperature speeds up the reaction rate, which can help a metal displace hydrogen from an acid.
Safety First!
Working with acids can be dangerous, so remember these safety tips:
Always wear appropriate safety gear, including goggles and gloves.
Work in a well-ventilated area.
Never mix acids with other chemicals unless you know what you’re doing.
If you get acid on your skin, rinse it immediately with plenty of water.
