Sodium sulfate is soluble in water. Hydrochloric acid is a water solution of HCl. Solubility is considered a physical property.
The blue color of copper II sulfate pentahydrate is a physical property, as it refers to an observable characteristic of the substance without changing its chemical composition. Chemical properties, on the other hand, describe how a substance reacts with other substances to form new products.
Sodium sulfate anhydrous can absorb water.
We can not answer this as we were not there to observe the experiment. Only YOU can answer this!
When magnesium sulfate dissolves in water, it undergoes a physical change, not a chemical change. The molecules of magnesium sulfate are simply dispersed in the water, but no new chemical substances are formed.
Copper sulfate dissolving in water is a physical change because the chemical composition of copper sulfate remains the same. Physical changes do not alter the chemical structure of a substance.
Grinding copper sulfate pentahydrate is a physical change because no new substances are formed during the process. The copper sulfate remains the same chemical compound, but its physical state is altered as it is broken down into smaller particles.
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
This is a homogeneous solution.
Sodium sulfate is a solid.
Sodium sulfate solution is neutral; the red litmus is purple.
When copper sulfate is added to water, it dissolves to form a blue solution of copper ions and sulfate ions. The dissolution process is a physical change where the copper sulfate molecules are surrounded by water molecules. This reaction does not involve any chemical bond formation or breaking, so it is classified as a physical change.
