Question

Which of the following is an anion with Valency two?

(A)Sulphate

(B) Carbonate

(C) hydride

(D)Phosphate. ​

Answer 1

Answer:

(A)Sulphate whose valency is 2 and it's an anion..

Answer 2

The anion with Valency two is (A)Sulphate.

• Anion is a negatively charged species formed as a result of the gain of electrons. an example is Cl-, Br- NO3- etc.
• Sulphate is (SO4)2- and the valency is -2.also, sulphate is an anion
• Carbonate is (HCO3)- and the valence is -1.
• Hydride is H- ion and the valence is -1.
• Phosphate is (PO4)3- and the valence is -3.
