Observe the following compounds. (i) CaCO ₃ (ii) MgSO ₄ (iii) BaCl ₂ (iv) Sr ( NO ₃ )₂ (v) MgBr ₂ (vi) MgCl ₂ The oxoacid salts of group II elements from the above list are
Options
- Ai, ii, iii, iv, v, vi
- Bi, ii, iv
- Ciii, v, vi
- Dii, v, vi
Correct answer
B. i, ii, iv
Step-by-step solution
The oxoacid salts of group II elements from the given list are CaCO ₃, MgSO ₄ and Sr ( NO ₃ )₂ because all salts contain acid and base with oxygen. CaCO ₃ is a salt of H ₂ CO ₃ and Ca ( OH )₂ . MgSO ₄ is a salt of H ₂ SO ₄ and Mg ( OH )₂ Sr ( NO ₃ )₂ is a salt of HNO ₃ and Sr ( OH )₂ .
