A salt is made up of a negative radical containing chlorine and it is associated with three oxygen atoms. The positive radical present in it is made up of two nonmetals. Which of the following statements is/are true regarding the salt?
(A) Both the positive and negative radicals are monovalent.
(B) Negative radical is generated from perchloric acid.
(C) The total number of atoms in one molecule of the salt is 9.
(D) The number of negative radicals present in one molecule of the salt is 2.
(E) The name of the negative radical has “ate” as suffix and does not have a prefix.

- Radicals are atom or group of atoms with positive or negative charges.
- The negative radicals are called anions and positively charged radicals are called cations.
- The negative radical (anion) which comprises of one chlorine and three oxygen atoms is chlorate radical (ClO3-).
- The positive radical (cation) comprises two nonmetals is ammonium radical (NH4+).
- Both the positive (NH4+) and negative radicals ( ClO3-) are monovalent.
- The negative radical is derived from chloric acid (HClO3)
- The compound formed by these radicals is ammonium chlorate( NH4ClO3).
- Total number of atoms present in one molecule (atomicity )of ammonium chlorate is 9.
(A) Both the positive and negative radicals are monovalent. This statement is true.
(B) Negative radical is generated from perchloric acid. The statement is false because the negative radical is derived from chloric acid (HClO3), not from perchloric acid (HClO4). The statement is false.
(C) The total number of atoms in one molecule of the salt is 9. In NH4ClO3 the number of atoms of each element is N -1, H -4, Cl -1 & O - 3. Therefore atomicity is 9. The statement is true.
(D) The number of negative radicals present in one molecule of the salt is 2. The statement is false . Only one negative radical is present (ClO3-) The statement is .false.
(E) The name of the negative radical has “ate” as suffix and does not have a prefix. The negative radical is chlorate. The statement is true.
Therefore the statements (A), (C) & (E) are true.
- Radicals are atom or group of atoms with positive or negative charges.
- The negative radicals are called anions and positively charged radicals are called cations.
