Water, pH and Macromolecules The main difference between an acid and a base is that 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 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 ANSWER DOWNLOAD EXAMIANS APP
