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
Water, pH and Macromolecules The main difference between an acid and a base is that acids are polar molecules and bases are not bases are polar molecules and acids are not bases donate hydrogen ions in water while acids accept hydrogen ions acids donate hydrogen ions in water while bases accept hydrogen ions acids are polar molecules and bases are not bases are polar molecules and acids are not bases donate hydrogen ions in water while acids accept hydrogen ions acids donate hydrogen ions in water while bases accept hydrogen ions ANSWER DOWNLOAD EXAMIANS APP
