If a substance can be dissolved in water what is that substance said to be?
If a substance can be dissolved in water, it is said to be hydrophilic or water-soluble. This means that the substance has an affinity for water and can form a homogeneous solution when mixed with it.
What is the molality of a solution containing 10.0g of Na2SO4 dissolved in 1000.0g of water?
To find the molality, we first calculate the moles of Na2SO4: 10.0g Na2SO4 * (1 mol Na2SO4 / 142.04g Na2SO4) = 0.0705 moles Na2SO4. Then, molality is calculated as moles of solute (Na2SO4) / kilograms of solvent (water): 0.0705 mol / 1.000 kg = 0.0705 mol/kg, which is the molality of the solution.
What is the term for a substance dissolved in water?
It is called a solute, which is dissolved in a solvent
How do you show that a substance is dissolved in water when writing the equation?
You can represent a substance dissolved in water by placing the chemical formula of the substance in parentheses followed by "(aq)" to indicate that it is in aqueous solution. For example, sodium chloride dissolved in water would be written as NaCl(aq).
What is the value of van t Hoff factor of Na2SO4?
The van't Hoff factor for Na2SO4 is 3, as it dissociates into 3 ions when dissolved in water: 2 Na+ ions and 1 SO4 2- ion.

In salt water the salt is the and the water is the?
Salt is the solute (the substance being dissolved) and water is the solvent (the substance doing the dissolving.
When sugar is dissolved in water is it a new substance?
No. The SUBSTANCE is still water, only now sugar is dissolved in it.
What is the cell that are brought by droplets of water and a dissolved substance?
The cells that are brought by droplets of water and a dissolved substance is called diffusion.
How do you show that a substance is dissolved in water when writing an equation?
To show that a substance is dissolved in water in a chemical equation, you can use the symbol (aq) next to the chemical formula of the substance. This indicates that the substance is dissolved in water to form an aqueous solution. For example, NaCl(aq) represents sodium chloride dissolved in water.
What is the term for a substance dissolved in water?
It is called a solute, which is dissolved in a solvent
What is a substance that releases hydroxyl ions when dissolved in water?
This substance is a base.

Something in which a substance dissolves?
"this property of water helps move substances from the roots of trees to their leaves"
What is the substance that is dissolved to form solution?
The solute. Solutions are formed when one substance (the solute) is dissolved into another (the solvent). For example, when a spoonful of sugar is dissolved in water, the sugar is the solute and the water is the solvent.
