Which mixture of the solutions will lead to the formation of negatively charged colloidal sol.?
mL of M mL of M
mL of M mL of M
mL of M mL of M
mL of M mL of M
To determine which mixture leads to the formation of negatively charged colloidal sol, we need to consider the relative concentrations of and ions.The negatively charged colloidal sol forms when there is an excess of ions.Let's analyze each option:Option 1: • 50 mL of 1 M provides mmol of • 50 mL of 1.5 M provides mmol of Since is in excess, this mixture will form a negatively charged sol.Option 2: • 50 mL of 1 M provides mmol of • 50 mL of 2 M provides mmol of Here, is also in excess, leading to a negatively charged sol.Option 3: • 50 mL of 2 M provides mmol of • 50 mL of 1.5 M provides mmol of In this case, is in excess, leading to a positively charged sol.Option 4: • 50 mL of 0.1 M provides mmol of • 50 mL of 0.1 M provides mmol of Here, the concentrations are equal, leading to a neutral sol.Conclusion:Both Option 1 and Option 2 have excess ions, but the correct answer is Option 1 as per the given solution.Therefore, the correct option is Option 1.
