Question

Как изменился цвет Купрума Сульфата во время разтворения в воде. Почему?

Answer 1

Изначально он был белого цвета, при растворении в воде он стал синим, т.к. есть сульфат меди безводный, белый, а есть кристаллогидрат CuSO4*5H2O он синего цвета, а при растворении в воде к нему присоединяются молекулы воды, ну можно показать так : CuSO4 + 5 H2O → CuSO4*5H2O. ну как-то так. вот если мы возьмём кристаллогидрат сульфата меди и испарим из него воду, он станет белым

Answer 2

Changes in the Color of Copper Sulfate During Dissolution in Water

When copper sulfate is dissolved in water, its color changes due to the interaction between the copper ions and water molecules. Initially, solid copper sulfate has a specific color, but when it is dissolved in water, the color of the solution changes. This change is due to the hydration of the copper ions and the resulting complex formation.

Initial Color of Copper Sulfate: - The initial color of solid copper sulfate is typically blue or bluish-green.

Color Change During Dissolution: - When copper sulfate is dissolved in water, the color of the solution changes. This change is due to the interaction between the copper ions and water molecules, leading to the formation of hydrated copper ions and a complex with water molecules.

Reason for Color Change: - The color change is primarily attributed to the hydration of the copper ions. When copper sulfate dissolves in water, the copper ions interact with water molecules, leading to the formation of hydrated copper ions. This complex formation alters the color of the solution.

In summary, the color change of copper sulfate during dissolution in water is a result of the interaction between the copper ions and water molecules, leading to the formation of hydrated copper ions and a complex with water molecules, which alters the color of the solution.
