Question

When the compound, Ca(NO3)2, is mixed with water, the Ca(NO3)2 is:

soluble because all Ca+2 compounds are soluble in water

insoluble because most Ca+2 compounds are insoluble in water

soluble because all NO3−1 compounds are soluble in water

insoluble because NO3−1 compounds are usually insoluble in water

Answer 1

Answer:

The answer t your question is below:

Explanation:

When a salt is mixed with water, it will form ions, these ions are soluble in water.

Example:    Ca(NO3)2    ⇒    Ca⁺²     +    2 NO₃⁻¹

Both Ca⁺² and NO₃⁻¹ are soluble in water.

Then the answer to your question is:

Soluble because all Ca+2 compounds are soluble in water

Soluble because all NO3−1 compounds are soluble in water
