The number of moles that are present in a liter of a solution is called Molarity. Mole is the unit of Molarity.The concentration of the solutes that are present in a solution refers to Osmolarity . The unit is osmol. This helps in observing the movement of water from one side to another side of a semipermeable membrane.

The main property of salts that helps to understand the differentiation between the molarity and osmolarity is the salts Ionization. One mole Na+ and one mole of Cl- is produced by the dissociation of a mole of sodium chloride occurs. The diffusion of water is the osmosis. Here, the one molar sodium chloride solution produces a osmotic pressure which is high than one molar glucose solution and this will not undergo dissociation.

Which phrase is an example of what electrostatic forces hold together?

Andreyy89

Answer:

Cs+ and Cl− in CsCl is an example of electrostatic forces that hold together.

Explanation:

The interaction that occurs between atoms that have an electric charge is called electromagnetic force. When the charges are at rest, the interaction between them is called electrostatic force. This force depends on the distance "r" between the atoms.

Depending on the sign of the charges that interact, electrostatic force can be attractive or repulsive. The electrostatic interaction between charges of the same sign is repulsive (two negative charges or two positive charges), while the interaction between charges of the opposite sign (a negative charge and a positive charge) is attractive. In the case of neutral charges against negative or positive charges, no force is generated.

Cs+ and Cl− in CsCl is an example of electrostatic forces that hold together. In this example you have a positively charged atom (Cs₊) and a negatively charged atom (Cl₋). As they are opposite charges they will attract.
