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 make nonpolar covalent bonds with the positively charged ions only form hydrogen bonds with the positively and negatively charged ions share electrons with the ions to make polar covalent bonds surround the ions because of their charge but do not form hydrogen bonds make nonpolar covalent bonds with the positively charged ions only form hydrogen bonds with the positively and negatively charged ions share electrons with the ions to make polar covalent bonds ANSWER DOWNLOAD EXAMIANS APP
