Which of the following sets of ions is present in calcium hydrogen phosphate,CaHPO₄? A) Ca²⁺ and PO₄^3- B) Ca²⁺ and HPO₄^2- C) Ca⁺ and HPO₄^- D) Ca³⁺ and HPO₄^3- E) Ca²⁺,H⁺,P^3-,and O^2-

Question

Quizplus · Accepted Answer

Calcium hydrogen phosphate, CaHPO₄, contains the ions Ca2+, H+, PO43-, and SO42-. Among the given choices, only option B contains all these ions: Ca²⁺ and HPO₄^2-. Option A is incorrect because it includes only one sulfur ion instead of two. Option C is incorrect because it includes only one phosphate ion instead of two. Option D is incorrect because it includes only one calcium ion instead of two. Option E includes all the required ions but also includes additional ions which are not present in calcium hydrogen phosphate, making it an incorrect choice.
