What happens when two solutions are added together?

The ions or molecules in two solutions can react to form a solid. A solid formed from two solutions is called a precipitate.

Why are solutions A and B hot?

On mixing A and B, the solution becomes warm. This means heat released in formation of new bonds between A and B molecules is more than the heat absorbed for the breaking of molecules of A and B.

What can happen when two materials are combined to make a new type of matter?

If materials combine chemically to make a new material, they undergo a chemical change. When oxygen in the air combines with iron, a chemical change happens.

What is mixture a combination of?

A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids.

When two solutions A & B mix the resulting solution becomes hot what type of solution it is?

Which type of deviation from Raoult’s law does it show? Warming up of the solution means that the process of mixing is exothermic, i.e., ΔmixingH is negative. This implies that the solution shows a negative deviation.

What typically happens when a hot solution solvent cools down?

Recrystallization involves dissolving the material to be purified (the solute) in an appropriate hot solvent. As the solvent cools, the solution becomes saturated with the solute and the solute crystallizes out (reforms a solid).

What happens when you mix a solid and liquid together?

The most common examples of dissolving involve a solid and a liquid, usually water. When a solid dissolves the solid (solute) and the liquid (solvent) form a very close intimate mixture called a solution. A solid will not dissolve in a liquid if its particles are unable to form links to the liquid particles.

How does matter combine separate or turn into something new?

Atoms of different elements join together to form molecules of a compound. A new substance is formed. This substance differs from the elements it is made of. An atom is the smallest bit of an element that is still that element, in the same way, a molecule is the smallest bit of a compound that is still that compound.

Why are mixtures important?

Mixtures and compounds are important combinations of elements. They are essential to the chemical processes that support living things, as well as those that occur every day in nonliving objects.

What makes substance different from mixture?

In chemistry: a pure substance consists only of one element or one compound. a mixture consists of two or more different substances, not chemically joined together.

When two liquids A and B are mixed heat is absorbed on forming a solution this show?

Since energy is released in the form of heat when the two liquids A and B are mixed, they show negative deviation from Raoult’s Law.

When solute and solvent is mixed the resulting solution found cooler What type of deviation is shown by the solution?

Answer: The solution shows a positive deviation.
