Question

Which of the following is not a mixed salt?

पर्याय

• NaKCO₃

• CaOCl₂

• KСaРО₄

• NaAlO₂

Answer 1

NaAlO₂

Explanation:

NaAlO₂ is not a mixed salt because it contains only one type of cation (Na⁺) and one type of anion \[\ce{(AlO^-2)}\]. Mixed salts contain two different cations or two different anions in the same salt.
