Which is a cause of polarity in water molecules?

Which is a cause of polarity in water molecules?

When the two hydrogen atoms bond with the oxygen, they attach to the top of the molecule rather like Mickey Mouse ears. This molecular structure gives the water molecule polarity, or a lopsided electrical charge that attracts other atoms. The end of the molecule with the two hydrogen atoms is positively charged.

Which of the following explains what is happening when sodium chloride dissolves in water?

Which of the following explains what is happening when sodium chloride dissolves in water? More hydrogen bonds are forming between water molecules.

When salt is dissolved in water is it a chemical change?

Therefore, dissolving salt in water is a chemical change. The reactant (sodium chloride, or NaCl) is different from the products (sodium cation and chlorine anion). Thus, any ionic compound that is soluble in water would experience a chemical change.

What happens to salt when it is dissolved in water?

When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.

When salt is dissolved in water What is pH 7?

A salt ‘X’ is dissolved in water (pH = 7), the resulting solution becomes alkaline in nature.

When common salt is dissolved in water then?

When common salt is dissolved in water, Boiling point of the solution increases. The boiling point of a substance is the temperature at which the vapor pressure of the substance equals atmospheric pressure.

What type of solution is perfume in air?

Answer: When you smell perfume on a person or by wafting perfume from a bottle, you are smelling a vapor of the scent compounds that have become volatilized (are in the gas phase) and diffuse through the air and into your nose. Perfume is a mixture of fragrant oils in an ethanol/water Solvent.

What are the 2 types of solutions?

The solutions are of two forms, depending on whether the solvent is water or not.

• Aqueous solution – When a solute is dissolved in water the solution is called an aqueous solution.
• Non-aqueous solution – When a solute is dissolved in a solvent other than water, it is called a non-aqueous solution.

What is the solution process?

Solutions are homogeneous mixtures of two or more substances whose components are uniformly distributed on a microscopic scale. Solvation is the process in which solute particles are surrounded by solvent molecules. When the solvent is water, the process is called hydration.

What is not example of solution?

In chemistry , a solution is a homogeneous mixture composed of two or more substances. Here Benzene in water is not an example of solution. Like dissolves like, since benzene and water are of different polarities they will form distinct layers and not dissolve.
