The polarity of water Polarity means that the molecule has both a positively and negatively charged end. More important‚ the polarity of water is responsible for effectively dissolving other polar molecules‚ such as sugars and ionic compounds such as salt. Ionic compounds dissolve in water to form ions. This is important to remember because for most biological reactions to occur‚ the reactants must be dissolved in water. Because water is able to dissolve so many common substances‚ it is known as
