Question

20 ml of 0.2M Al2(SO4)3 is mixed with 20ml of 6.6 M BaCl2 , the concertration of Cl - ion in solution is 1) 0.2 2) 6.6 3) 0.02 4) 0.06

Answer 1

Thank you for asking this question. Let me help you with this question.
well, the answer to this question is 6.6 M. Hence option (2) is correct. The reason is that in this reaction, the concentration of chloride ions is the same as the concentration of BaCl₂ as chloride ions are present in this only. It is given that 6.6 M of BaCl₂ is used in this reaction. Hence, the concentration of chloride ions will be 6.6 M.
Hope it will help you. Thanks.
