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.

Why boiling point of H2O is greater than H2S?
Although both molecules are polar and have similar masses, the O-H bond in water is highly polar, producing a dipole movement in the overall molecule towards O. The S-H is also polar and produces a dipole movement towards S, but it is not as strong a separation of charge as that produced by O-H. This results in H20 molecules being more strongly attracted to each other by Hydrogen bonding, than H2S molecules which are attracted to each other due to only dipole-dipole attraction. Stronger attraction between molecules means it takes more energy to separate them into the gas phase, making it have a higher boiling point.
Why is hemoglobin attracted towards magnet?
because they feel like it :)
Why sand is not attracted towards magnet?
because sand does not have metal in it
Explain the rule like dissolves like more specific please. What is the contribution of the atom's structure?
The expression "like dissolves like" refers to polar molecules dissolving other polar molecules, and nonpolar molecules dissolving others with similar characteristics. To describe this process, electronegativity must be clarified: Electronegativity describes an atom's attractive strength to electrons; higher electronegativity means stronger electron pull towards it. Each atom needs 8 electrons to fulfill its outer valence shell, and so the closer it gets to that number the stronger is their attraction to electrons. Flourine would be the most electronegative, and Cesium would be the least. This attraction power dictates whether it has a positive and negative dipole (like magnets). Water is a polar solvent, and oxygen (an EN atom) creates a net dipole with hydrogen that will attract other dipole molecules. When multiple water molecules surround and are attracted to its neighbors, it is effectively dissolved. Now, oil spots and other nonpolar moles are clumped together because they don't have dipole forces. To summarize, electronegative atoms gives molecules polarized positive and negative charges, which turns them into polar molecules. It is attacted to other molecules with the same +/- charge, and repelling away all other nonpolar molecules.
Why does the anode decrease in size during aluminium electrolysis?
My thought is that ,that when the electric current is passed through the electrolyte the aluminium from the anode gets attracted towards the cathode as it has positive charge & rest of the impurities get dissolved in electrolyte or get collected in the beaker.therefore,this way the anode decreases.
Why are polar liquids always attracted towards the charged rod and not repelled?
because they have a positive and negative end
Are electrons negatively charged or is it just a convention then how do tell it is attracted towards the positive?
electrons have a negative charge...or atleast that's what i was taught:P
Why is an alpha particle attracted to a negative plate?
Alpha particles are deflected towards negative plates because they are positively charged.
Why water molecules have positive and negative poles?
Water(H2O) is a polar molecules due to the electronegative of oxygen (O). O draws the electrons towards it creating a negative charge over its atom. The hydrogen in comparison is positive in comparison.
As a cation moves towards an anion what happens to the energy?
Energy will decrease because they are attracted to eachother. A cation has a positive charge and an anion has a negative charge.
Which atomic particle carries a positive charge?
it would be probably cation as it carries a positive charge in electrolysis and is attracted towards negative electrode
Are molecules attracted towards each other by gravity?
They better be! Electrical forces are much stronger than gravitational (for the same charged mass).
What is hydrochloric acid in strucural form?
Hydrochloric acid is HCl dissolved in water When dissolved in water the Hydrogen (H) and the Chlorine (Cl) separate. The Hydrogen ion has a positive charge, as it has one fewer electron than it would have as a hydrogen atom, and the Chloride ion has a negative charge, it having one extra electron. The H+ ion reacts with H2O (water molecules) to form [H3O]+ whereas the Cl- ion is quite happy to sit around on its own. Interestingly, water molecules are polar, their O bit is slightly negative whilst their H bits are slightly positive. This means that the water molecules near the Chloride ions will tend to point their H atoms towards the Cl-. Hope this helps, L
What is the purpose of the electrical current in gel electrophoresis?
The electrodes are able to pull the fragments towards the ends of the gel. If you're using DNA, which has a negative charge, it will be attracted to the positive electrode.
Why are helium balloons attracted towards you?
static electricity

When are hydrogen bonds formed?
Short Answer: a partially positive hydrogen atom gets attracted to a partially negatively charged atom. _______________________ Take water for example. There is an Oxygen atom (which pulls electrons towards it-- making it partially negative) There are also two hydrogen atoms. The (negatively charged) electron on each H atom is being pulled towards the O atom, making the Hydrogen partially positive. Now, when two water molecules come together, the partially positively charged H's on one water molecule are attracted to the partially negatively charged O's on the other molecule. This attraction between oppositely charged atoms on different molecules creates a 'hydrogen bond'.
