Which of the following statements best describes the Hardy Schulze rule?

Key Points

• The amount of electrolyte required for the coagulation of a definite amount of a colloidal solution is dependent on the valency of the coagulating ion describes the Hardy Schulze rule.
• The rule states that ions with higher valency are more effective in causing coagulation of colloids compared to ions with lower valency.
• This principle is important in understanding the stability of colloidal solutions and the process of coagulation.
• It helps in predicting the amount and type of electrolyte needed to destabilize a colloidal system.

Additional Information

• Colloids are mixtures where one substance is dispersed evenly throughout another.
• The Hardy Schulze rule is named after the scientists who discovered it.
• It is a key concept in colloid chemistry and is used in various industrial and research applications.
• Understanding this rule is crucial for processes like water purification, where coagulation is used to remove impurities.
