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