At ambient conditions (the temperatures and pressure in an ordinary lab room) magnesium sulfate will be solid. It will also dissolve easily in water to become aqueous; magnesium sulfate is the chemical formula for Epsom Salts. It will hydrate easily in the presence of humid air - but remain solid. You really won't get it to melt - it decomposes before melting - so you wouldn't get it as a liquid, nor would you get it to boil to become a gas. Like any solid, it will sublime just a little bit at low pressures but the vapor pressure of the salt is so low that for all practical purposes we wouldn't worry about it ever evaporating/subliming any more than we worry about table salt evaporating.
Sodium sulfate can exist in both forms: as a solid (crystalline powder) and in aqueous solution when dissolved in water.
Magnesium phosphate is typically a solid compound at room temperature. In aqueous solutions, it can dissociate into its ions, magnesium (Mg2+) and phosphate (PO43-).
Magnesium sulfate is a solid at room temperature. It is a white crystalline compound commonly known as Epsom salt.
This solution is a liquid.
No. Like virtually all ionic compounds copper II sulfate is a solid at room temperature. It is, however, soluble in water so you would be able to find an aqueous solution of t.
Magnesium chloride can exist as a solid, liquid, or aqueous solution depending on its physical state. Solid magnesium chloride is a crystalline substance, liquid magnesium chloride is a molten form, and aqueous magnesium chloride is a solution in water. It does not exist as a gas under normal conditions.
Sodium sulfate can exist in both forms: as a solid (crystalline powder) and in aqueous solution when dissolved in water.
Magnesium phosphate is typically a solid compound at room temperature. In aqueous solutions, it can dissociate into its ions, magnesium (Mg2+) and phosphate (PO43-).
The white solid precipitated when an aqueous solution of barium chloride is mixed with an aqueous solution of sodium sulfate is named "barium sulfate" and has the formula BsSO4.
No, Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral.
The solution of magnesium sulfate and water can be separated by a process called evaporation. The solution is heated until the water evaporates, leaving behind the solid magnesium sulfate. The remaining magnesium sulfate crystals can then be collected and the water can be condensed back into a liquid form through condensation.
No. Magnesium oxide is not soluble in water. On contact with water it will form magnesium hydroxide.
Magnesium sulfate is a solid at room temperature. It typically appears as a white crystalline substance and is commonly known in its hydrated form as Epsom salt. When dissolved in water, it dissociates into magnesium and sulfate ions, but in its pure form, it is not a gas.
MgCrO4 (magnesium chromate) is typically a solid at room temperature. It is an ionic compound that can dissolve in water, forming an aqueous solution, but in its pure form, it exists as a solid.
Normally it would be crystalline or a solid powder like substance soluble in water. Change would be based on conditions you impose.
Magnesium Nitride is a greenish yellow powder at room temperature. So it's solid. I think you are a little confused on your terminology aqueous refers to something being dissolved in water. Magnesium Nitride reacts with water to produce ammonia gas. So Magnesium Nitride could never be an aqueous solution.
Sodium sulfate can exist in an aqueous solution but it can also exist on its own as a crystalline solid.
