# Do bases taste sharp?

Back in the day, a chemist would often report on the taste of a new chemical substance. Acids traditionally tasted sour and sharp. Try a sip of lemon juice, which will certainly take the smile off your face. Most things that we eat that taste good, i.e. wine, vinegar, cheeses, tomatoes, are in fact quite acidic. The most basic thing that we eat is quite probably egg-white, $p H \cong 8 - 9$; the soapy sliminess and bitterness of egg white are quite typical of a base.
