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

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