Question:
Which metal reacts most with dilute acid to displace hydrogen?
Which metal reacts most with dilute acid to displace hydrogen?
Show Hint
Metals higher in the reactivity series (like Zinc) react more readily with dilute acids to displace hydrogen.
Updated On: Nov 25, 2025
- Zinc
- Copper
- Silver
- All react the same
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding reactivity with dilute acids.
The reactivity of a metal with dilute acid to displace hydrogen is governed by its position in the reactivity series. Metals higher in the reactivity series displace hydrogen more readily.
Step 2: Comparison of metals.
- Zinc (Zn) is a highly reactive metal and reacts readily with dilute acids like HCl to release hydrogen gas. - Copper (Cu) and Silver (Ag) are much less reactive and do not react with dilute acids to displace hydrogen under normal conditions.
Step 3: Conclusion.
Thus, Zinc reacts most with dilute acid to displace hydrogen, corresponding to option (A).

- Given below are two statements :
1 M aqueous solution of each of $ Cu(NO_3)_2 $, $ AgNO_3 $, $ Hg_2(NO_3)_2 $; $ Mg(NO_3)_2 $ are electrolysed using inert electrodes, Given : $ E^0_{Ag^+/Ag} = 0.80V $, $ E^0_{Hg_2^{2+}/Hg} = 0.79V $, $ E^0_{Cu^{2+}/Cu} = 0.34V $ and $ E^0_{Mg^{2+}/Mg} = -2.37V $
Statement (I) : With increasing voltage, the sequence of deposition of metals on the cathode will be Ag, Hg and Cu
Statement (II) : Magnesium will not be deposited at cathode instead oxygen gas will be evolved at the cathode.
In the light of the above statements, choose the most appropriate answer from the options given below :- JEE Main - 2025

Consider the following half cell reaction $ \text{Cr}_2\text{O}_7^{2-} (\text{aq}) + 6\text{e}^- + 14\text{H}^+ (\text{aq}) \longrightarrow 2\text{Cr}^{3+} (\text{aq}) + 7\text{H}_2\text{O}(1) $
The reaction was conducted with the ratio of $\frac{[\text{Cr}^{3+}]^2}{[\text{Cr}_2\text{O}_7^{2-}]} = 10^{-6}$
The pH value at which the EMF of the half cell will become zero is ____ (nearest integer value)
[Given : standard half cell reduction potential $\text{E}^\circ_{\text{Cr}_2\text{O}_7^{2-}, \text{H}^+/\text{Cr}^{3+}} = 1.33\text{V}, \quad \frac{2.303\text{RT}}{\text{F}} = 0.059\text{V}$- JEE Main - 2025
