Is it true When water dissolves sugar the positive ends of the water moecules are attracted to the negative ends of the sugar molecules?
Generally, when a molecule is dissolved in water, the process called hydration occurs.
This process consists in the creation around the polar or ionic parts of the dissolved molecule of a shell of water molecules that are bonded to solute via polar bonds (called hydrogen bonds).
This is a fundamental process in solution formation. As a matter of fact, it deeply influences the spontaneous solution formation by participating to the solution free energy and renders the water a very good solvent, differently from other liquids that are not able to form such bonds.

Why oil does not dissolve in water?
Water dissolves substances because it's hydrogen bonds make it a polar molecule. Thus, the positive and negative ends of the water molecules attract the negative and positive ends (respectively) of substances, thus pulling them apart and dissolving the substance. Oil, however, is a nonpolar substance, so it is not attracted to the polarity of water.
Why water dissloves so many different substances?
Water dissolves many substances but its molecules have both a positive and negative side. Each part of the molecule can bond with the molecules of many other substances and create a new solution. This is the reason water is considered the universal solvent.
What is the most important role of hydrogen bonding between water molecules?
The molecules of water are held together by hydrogen bonding between molecules.These are electrostatic bonds (attraction forces between opposite charges) that hydrogen makes with the oxygen of neighbouring molecules. Hydrogen, when bonded to oxygen to form water molecules, is slightly positive and the oxygen in the water molecule is slightly negative. Hydrogen gets attracted to the neighbouring slightly negative oxygen atoms.This is great for life on Earth because small molecules the size of water tend to be gases but water is a liquid. It is a liquid due to the hydrogen bonding between molecules.
What is phase of sugar in sugar water solutions. is it solid or liquid phase?
In solution, the sugar is no longer in a state of solidity or fluidity. once dissolved, it is divided into charged particles or smaller mollecules, which are attracted to either the positive or negative poles of the water molecules. The sugar molecules are therefore aqueous, not solid, liquid or gas.
Why is water both adhesive and cohesive?
Cohesion in water is the water being 'sticky' or attracted to itself. Adhesion in water is when the water is 'sticky' or attacted to other surfaces. Water is cohesive and adhesive because of it's properties. The oxyogen and hydrogen molecules are bonded together and are polar. Beacuse the molecules are polar the particales are therefore attracted to each other from negative to positive end (cohesion), but are also atracted to other particles in other surfaces, again positive to negative poles (adhesion). It's very important that water be both cohesive and adhesive for being good for solutions and other functions.
What happened when salt dissolves in water?
The negatively charged ions (Cl-) and the positively charged ions (Na+) become solvated which is the process where a solute dissolves. The ions are surrounded by solvent molecules (water). For water bonds the oxygen is slightly negative and the hydrogen molecules are slightly positive; the shared electrons are pulled closer to the oxygen. The sodium ions are attracted to the oxygen's negative charge and the chloride ions are attracted to the hydrogen's negative charge.
Water dissolves many ionic and molecular compounds because of its what?
Water is a highly polar molecule which means that one side of the molecule is slightly positive and the other is slightly negative. This means that water molecules are attracted and can form weak bonds with molecules that also have positive sides and negative sides (polar molecules). Basically, the positive side of the water molecule is attracted to the negative side of the polar molecule and the negative side of the water molecule is attracted to the positive side of the polar molecule. Is this way the water is able to surround and separate the polar molecules. The story is much the same for an ionic compound which contains a mixture of positive and negative ions. The positive side of the water molecules surround the negative ions and the negative side of the water molecules surround the positive ions.
When an ionic molecule dissolves in water what does the water molecule do?
Surrounds the ions with the hydrogen, positive end, attracted to the negative ion ( Cl -, for instance ) and the oxygen, negative end, attracted to the positive ion ( Na +, for instance ).
When NaCl is dissolved in water negative end of the water molecules is attracted towards what?
Ion-dipole attraction dictates that the negative pole of a water molecule will be attracted to the sodium cation and the positive pole of a water molecule will be attracted to the chloride anion.
Do ions repel water?
Ions and Water Ions do not repel water. In fact, they actually attract water molecules. When an ionic compound like salt (sodium chloride) dissolves in water: Positive Ions: The positive sodium ions (Na+) are attracted to the negative oxygen end of the water molecules. Negative Ions: The negative chloride ions (Cl-) are attracted to the positive hydrogen ends of the water molecules. This attraction between the ions and water molecules is called hydration. The ions become surrounded by water, which helps them break apart and go into solution. So in simple terms, ions are attracted to and interact with water, rather than repelling it. The hydration of ions is an important part of how they dissolve in water.
Does Sugar dissolves in water because the positive ends of the sugar molecules are pulled off the solute surface by the negative ends of the water molecules?
Yes
Why does CO2 dissolve in water?
Carbon dioxide (CO2) dissolves in water because of its polar nature. The molecules of water are polar, meaning they have positive and negative charges on different ends. CO2 is also a polar molecule, so it is attracted to the water molecules. This attraction allows CO2 to dissolve in water, forming a solution.
What happens on the molecular level when an ionic solid like NaCl dissolves?
When NaCl dissolves in water, the polar water molecules surround the Na+ and Cl- ions. The positive end of the water molecule (-) is attracted to the Cl- ion while the negative end of water molecule (+) is attracted to the Na+ ion. This breaks the ionic bonds between Na+ and Cl- ions and allows them to disperse in the water, resulting in the formation of a NaCl solution.
How do water molecules dissolves a salt?
The water molecules move around the salt ions In water, the salt separates into positive and negative ions.
Why do carbohydrates dissolve so easily in water?
Water is a polar molecule, meaning that the hydrogen end has a negative charge, while the oxygen end has a positive charge. When other polar molecules are exposed to these charges they split apart. In salt the sodium has a positive charge that is attracted to the hydrogen's negative charge, and a the chloride has a negative charge that is attracted to oxygen's positive charge.
When Salt dissolves in water what forces or attractions exist to attract them together?
When salt dissolves in water, there are mainly two types of attractions present: ionic bonding and hydrogen bonding. The positively charged sodium ions (Na+) are attracted to the negative oxygen atoms in water molecules due to ionic bonding. Meanwhile, the negatively charged chloride ions (Cl-) are attracted to the positive hydrogen atoms in water molecules through hydrogen bonding. These attractions help break apart the salt crystal and allow it to dissolve in water.
How do potassium chloride particles bond to water particles?
Potassium chloride is an ionic compound, composed of positive potassium ions and negative chloride ions. When it dissolves in water, the ions separate and become surrounded by water molecules. Water is a covalent compound, but it is polar, which means that one end (the oxygen) is a little bit negative, and the other is a little bit positive. The slightly negative ends are attracted to the positive potassium ions and the slightly positive ends are attracted to the chloride ions. These are electrostatic attractions.
