Question

Which of the following is calcium super phosphate?

• A. $ Ca{{(HP{{O}_{4}})}_{2}}.{{H}_{2}}O+2CaS{{O}_{4}}.2{{H}_{2}}O $
• B. $ C{{a}_{3}}{{(P{{O}_{4}})}_{2}}+2CaS{{O}_{4}} $
• C. $ CaS{{O}_{4}}+CaO $
• D. $ Ca{{({{H}_{2}}P{{O}_{4}})}_{2}}.{{H}_{2}}O+CaS{{O}_{4}} $

Answer 1

Answer: (A)

Mixture of calcium dihydrogen phosphate and gypsum is known as super phosphate of lime. The formula is: $ Ca{{({{H}_{2}}P{{O}_{4}})}_{2}}.{{H}_{2}}O+2(CaS{{O}_{4}}.2{{H}_{2}}O) $
