Question

When alkali dissolves in water ________ type ions are formed.
1) cation
2) anion
3) Both cation
4) Both anion​

Answer 1

Ionic bonds are formed between cations and anions.
A cation is formed when a metal ion loses a valence electron while an anion is formed when a non-metal gains a valence electron. They both achieve a more stable electronic configuration through this exchange.
Ionic solids form crystalline lattices, or repeating patterns of atoms, with high melting points, and are typically soluble in water.
Key Terms

electrolyte: An ionic compound which dissolves in H2O, making the resulting solution capable of conducting electricity.
electronegativity: The tendency of an atom to attract electrons to itself.
cation: A positively charged ion.
anion: A negatively charged ion.

Answer 2

Dissolution of alkali in water results in the formation of anions

• An alkali is a type of compound that is basic in nature and has the presence of a hydroxide group in it.
• When an alkali is dissolved in water, a dissociation reaction takes place due to which the alkali gets dissolved into its components.
• This leads to the formation of OH⁻ ions (hydroxide ion), which is an anion, in the water with its counterpart as well.

Thus, when alkali dissolves in water, (Option 2) anion-type ions are formed.
