When a molecular compound like sugar dissolves, and individual sugar molecules are suspended in the water. When a molecular compound dissolves in water, none of the bonds in the molecule are broken. However, the bonds between the molecules are broken (the bonds between two different molecules are what hold sugar together, making it a solid).
When you dissolve an ionic compound, like table salt(which is called sodium chloride with formula NaCl), it is slightly different. Here, the bonds in the salt crystals also break down as before, but now the bond between the sodium (Na) and the chloride (Cl) are also broken. This results in a solution of ions in the water, composed of Na+ and an equal amount of Cl-.

∙ 14y agowhen a solid dissolves in water (or any liquid) the particlesbreak up. in a solid, all particles are fixed together and cannot move. a liquid will break up the particles, making them too small to see.
for example, if you were to stir sugar in water, the sugar will break up, and 'disappear', but it will still taste of sugar as it is still present.

If you sprinkle salt into a cup of water what happens to the salt before it dissolves and Why?
The salt breaks down into ions because the covalent water compound is bound together tightly.
What If you sprinkle salt into a cup of water what happens to the salt before it dissolves and why?
The salt breaks down into ions because the covalent water compound is bound together tightly.
Are covalent compounds soluble?
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
