Question

Disodium Potassium Phosphate (Na₂KPO₄) is a ____ salt.

• A. Complex
• B. Double
• C. Mixed
• D. Basic

Answer 1

The correct option is C

Mixed

Explanation:

• A mixed salt has fixed proportion of two salt sharing either a common cation or an anion.
• Na₂KPO₄ (disodium potassium phosphate) has two salts: sodium phosphate (Na₃PO₄) and potassium phosphate (K₃PO₄) sharing the common anion PO₄^2-.. Thus, it is a mixed salt.

Therefore, the correct option is (C).
