To find the flocculation value of HCl for the colloid, we can follow these steps: ### Step 1: Understand the Concept of Flocculation Value The flocculation value is defined as the minimum amount of electrolyte (in millimoles) required to cause complete coagulation of 1 liter of colloidal solution. ### Step 2: Calculate the Moles of HCl Added We know that 0.73 g of HCl was added to the colloid. To find the number of moles of HCl, we use the formula: \[ ...
