Water, pH and Macromolecules Salt dissolves well in water as water molecules surround the ions because of their charge but do not form hydrogen bonds share electrons with the ions to make polar covalent bonds form hydrogen bonds with the positively and negatively charged ions make nonpolar covalent bonds with the positively charged ions only surround the ions because of their charge but do not form hydrogen bonds share electrons with the ions to make polar covalent bonds form hydrogen bonds with the positively and negatively charged ions make nonpolar covalent bonds with the positively charged ions only ANSWER DOWNLOAD EXAMIANS APP
