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