It is not advisable to differentiate acids and bases through taste because some are toxic and inedible. But for those that are safe to ingest, acid tastes sour like vinegar and lemonade. Alkaline or basic solutions taste bitter like if you'vetried tasting soap detergent as you peel it open with your teeth.
<span>Acid is a molecule capable of
donating hydrogen ion and they form aqueous solutions with a sour taste while
base is a substance that accepts proton from proton donor and in aqueous solution,
they have an astringent or bitter taste. Moreover, a good example for base is
sodium hydrogen carbonate as baking soda or baking powder and for acid, the
most common example is the acetic acid or vinegar.</span>
