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.
Water has a polar molecule.
Polarity
Ionization
Water is a polar molecule, and therefore dissolves other polar substances and many ionic compounds because of its partially positive hydrogen end and its partially negative oxygen end. However, petrol is a nonpolar substance and only dissolves other nonpolar substances.
Anything that dissolves in water, such as sugar or salt, does so because it has an attraction on the molecular level; sugar molecules attract water molecules. This attraction helps to overcome the attraction that water molecules have for each other, which holds them together in a frozen form.
calcium metal dissolves in water because as it gets put in the water, the calcium quickly bonds with the oxygen atom in H2O. so it leaves that with hydrogen, therefore, hydrogen is produced when calcium dissolves in water
Water is also a good solvent due to its polarity. Substances that will mix well and dissolve in water (e.g. salts) are known as hydrophilic (water-loving) substances, while those that do not mix well with water (e.g. fats and oils), are known as hydrophobic (water-fearing) substances. The ability of a substance to dissolve in water is determined by whether or not the substance can match or better the strong attractive forces that water molecules generate between other water molecules. If a substance has properties that do not allow it to overcome these strong intermolecular forces, the molecules are pushed out from the water, and do not dissolve. Contrary to the common misconception, water and hydrophobic substances do not repel, and the hydration of a hydrophobic surface is energetically, but not entropically, favorable
Water dissolves some molecular compounds because water is a polar molecule.
because it is a polar molecule
ionic bonding
water, because of its polarity. This is caused by the oxygen molecule having a higher electron affinity, which means that the electrons of the hydrogen molecules more or less hang out around the oxygen causing the oxygen to be partially negative and the hydrogen ends to be partially positive. This is what is called a dipole moment which is why ionic (positive or negatively charged) and molecular (polar covalent) compounds are able to dissociate in the solvent(water).
Water can dissolve some ionic compounds as well as some molecular compounds because of its polarity. It is polar enough to dissolve ionic compounds into their ions. Water does not dissolve molecular compounds by breaking covalent bonds, but through intermolecular forces.
Like dissolves like. Water is polar solvent and hence it dissolves ionic and polar compounds.
Solubility of a substance in water depends on the type of interaction predominates in the compound and the solvent.The solubility of any compound follows the principle "like dissolves like".So if a covalent molecular compound is polar then it dissolves in a polar solvent and if it is non polar or hydrophobic then it dissolves in a nonpolar solvent
Yes. Water is known as a very good solvent mostly because of its ionic structure. Mostly water dissolves ionic compounds because of the like dissolves like.
Water does not have a pH of 14. By convention water has a pH of 7. Water dissolves ionic compounds because it is a polar liquid.
molecular formula is referred to water because they are covalent compounds while formula mass for aluminum chloride because they are ionic compounds

Molecular (covalent) compounds are not dissociated in water.
