The molarity of NO ₃ ⁻ in the solution after 2 ~L of 3 M AgNO ₃ is mixed with 3 ~L of 1 M BaCl ₂ is

Options

  1. A1.2 M
  2. B1.8 M
  3. C0.5 M
  4. D0.4 M

Correct answer

A. 1.2 M

Step-by-step solution

2 ~L of 3 M AgNO ₃ will contains 6 moles of AgNO ₃ 3 ~L of 1 M BaCl ₂ will contain 3 moles of BaCl ₂ 2 AgNO ₃+ BaCl ₂ 2 AgCl + Ba ( NO ₃ )₂ So, 6 moles of AgNO ₃ will react with 3 moles on BaCl ₂ it means, two solution will react completely to form 3 moles of Ba ( NO ₃ )₂ 6 moles of NO ₃⁻ ions in 2+3=5 ~L solution Hence, molarity of NO ₃⁻= 6 5 =1.2 M
