What salt is formed by the reaction of potassium hydroxide and hydrochloric acid?

potassium chloride

Explanation:

Double displacement reaction is one which involves exchange of ions. Neutralization is a type of double displacement reaction in which an acid combines with a base to form salt and water, the reaction is called as neutralization reaction.

Thus the salt formed is potassium chloride which has the chemical formula .

Explanation:

CH₃C(CH₃)=CH-CH₂-CH₃ ( 2 - methylpent-2-ene)

Cl₂ ⇒ Cl⁺ + Cl⁻

Cl⁺( electrophile)

CH₃C(CH₃)=CH-CH₂-CH₃  + Cl⁺ ( electrophile)  ⇒ CH₃C⁺(CH₃)-C(Cl)H-CH₂-CH₃ (  intermediate )

CH₃C⁺(CH₃)-C(Cl)H-CH₂-CH₃ + Cl⁻  ⇒ CH₃CCl(CH₃)-C(Cl)H-CH₂-CH₃ ( final product )

It is electrophilic addition reaction.
