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

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