Write an equation that represents the action in water of calcium hydroxide as an Arrhenius base

Explanation:

Calcium hydroxide  = Ca(OH)₂

Water  = H₂O

An Arrhenius base is a substance which interacts with water to yield excess hydroxide ions, OH⁻ in an aqueous solution.

  The reaction in water;

           Ca(OH)₂   →  Ca²⁺  + 2OH⁻

The medium of this reaction is water.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
