When solid kbr is dissolved in water the solution gets colder is this endothermic or exothermic?
The process of dissolving solid KBr in water and the resulting decrease in temperature is an exothermic reaction. This means that heat is being released to the surroundings during the dissolution process.
Which of the following does not increase the rate of dissolving a solid in water?
Increasing the pressure decreases the volume of gas bubbles and does not increase the rate of dissolving a solid in water.
When a certain solid dissolves in water the solution becomes cool Is ΔHsoln for this solute positive or negative?
ΔHsoln for this solute is negative. The solution becomes cool because the dissolving process absorbs heat from the surroundings, leading to a decrease in temperature. This indicates an endothermic process, where energy is absorbed during the dissolution of the solid in water.
Dissolving an electrolyte in water results in the formation of?
ions, which allow the solution to conduct electricity.
What is made up of two components the most common configuration being a solid solute and a liquid solvent?
This is known as a solid-liquid solution where the solid solute dissolves in the liquid solvent to form a homogeneous mixture. An example is salt (solid) dissolving in water (liquid) to form a saltwater solution.

Will cooling a solution of salt crystals and water slow down the dissolving rate?
Yes; the solubility of solids in liquids decrease when the temperature decrease.
Which of the following does not increase the rate of dissolving a solid in water?
Increasing the pressure decreases the volume of gas bubbles and does not increase the rate of dissolving a solid in water.
A solid and a liquid can form a mixture?
Yes, a solid and a liquid can form a mixture through a process called dissolution, where the solid is dissolved in the liquid. Examples include sugar dissolving in water to form a sugar solution and salt dissolving in water to form a saline solution.
What is the mass percent of a solution prepared by dissolving 18.9 grams of solid into 39.5 grams of water?
32.4

When something is dissolving is it a solid or an aqueous solution?
When a solid such as table salt is placed in a liquid that dissolves it (a solvent) such as water, it dissolves and passes into solution. When it is all dissolved there is no solid left, only the liquid salt solution. It is still solid while it is dissolving as the dissolution action can only take place at the surface of the solid. Removal of salt ions (sodium and chlorine atoms) from the solid exposes more solid underneath until all the solid is dissolved.
Does a saltwater solution form when a solid dissolves in a gas?
A saltwater solution forms when salt is dissolved in water. Solids do not dissolve in gasses, though they can sometimes change from a solid state to a gaseous state in a process known as sublimation. This is not analogous to dissolving.
How do you reclaim ammonium nitrate after dissolving it in water?
To reclaim ammonium nitrate after dissolving it in water, you can evaporate the water by heating the solution, leaving behind solid ammonium nitrate. Alternatively, you can also perform a chemical reaction to precipitate ammonium nitrate out of the solution, such as adding a more soluble salt to the solution to form insoluble ammonium nitrate.
Why dissolving is happening?
materials have ability to get an equilibrium state i,e they try to be stable add sugar in water sugar highly concentrated solid water neutral so they become equilibrium by dissolving process as homogeneous solution
