Question

Identify the cation and anion present in the H2SO4

Answer 1

Cation present in H$_2$SO$_4$ is $H^{+}$

Anion present in  H$_2$SO$_4$ is $SO_{4} ^{2-}$

Reason -

H$_2$SO$_4$ dissociates into $H^{+}$ and $SO_{4} ^{2-}$.

H$_2$SO$_4$ ------------------->   $2H^{+} + SO_{4} ^{2-}$

Here, $H^{+}$ is the cation (positively charged ion) and $SO_{4} ^{2-}$ is the anion (negatively charged ion)

What are cations and anions?

• Cations are positively charged ions. They are formed when a metal loses its electrons. They lose one or more electron but do not lose any protons. As a result, they possess a net positive charge. Some examples of cations are Calcium ($Ca^{2+}$), Potassium ($K^{+}$), Sodium ($Na^{+}$).

• Anions are negatively charged ions and are formed when non-metal  gains one or more than one electron but protons remain the same. As a result, they possess a net negative charge. Some examples of anions are Iodide ($I^{-}$), Hydroxide ($OH^{-}$).

Answer 2

The cation and anion present in the $H2SO4$ is $H+$ and $HSO4^{-}$

Explanation:

• Cation present in $H2SO4$ is $H+$  
• Anion present in $H2SO4$ is $HSO4^{-}$
• $H2SO4$ dissociates into  $H+$ and $HSO4^{-}$
• $H2SO4$ → $H+$  + $HSO4^{-}$  

Here, the cation is the positively charged ion and the anion is the negatively charged ion.

Anions :-

Anions are negatively charged particles which are  formed when non metal gains one or more electrons.

They have the same number of protons.

They possess a net negative charge.

Examples of anions are iodide $I^{-}$ and hydroxide $OH^{-}$

Cations  

Cations are positively charged ions which are formed when a metal loses one or more  electrons.

They lose one or more electrons but do not lose any protons. As a result, they possess a net positive charge.

Some examples of cations are Calcium ($Ca^{2+}$), Potassium ($K^{+}$), Sodium ($Na^{+}$).
