Metal ions that precipitate together can be separated by changing the pH of the solution.

Question

Quizplus · Accepted Answer

This is true because the solubility of many metal ions depends on the pH of the solution. By adjusting the pH, some metal ions may become insoluble and precipitate out of solution, while others may remain soluble and can be separated from the precipitate. This process is commonly used in analytical chemistry for the separation and identification of different metal ions in a sample.
