Current Question (ID: 8642)

Question:

$\text{The incorrect statement among the following regarding hydrogen is -}$

Options:

1. $\text{Hydrogen never acts as a cation in ionic salts}$
2. $\text{Hydronium ion, } \text{H}_3\text{O}^+\text{, exists freely in a solution}$
3. $\text{Dihydrogen does not act as a reducing agent}$
4. $\text{Hydrogen has three isotopes of which Protium is the most common}$

Solution:

$\text{Hint: Properties of hydrogen}$ $\text{In ionic salts, hydrogen never behaves as cation, but behaves as anion } (\text{H}^-)\text{.}$ $\text{H}_3\text{O}^+ \text{ exists freely in solution.}$ $\text{Dihydrogen acts as a reducing agent.}$ $\text{Hydrogen has three isotopes.}$ $\text{Protium } (^1_1\text{H})$ $\text{Deuterium } (^2_1\text{H})$ $\text{Tritium } (^3_1\text{H})$ $\text{Protium is the most common isotopes of hydrogen with an abundance of 99.98\%.}$
