Acid and Bases

Most of us have learned about acids and bases. We have learned that acids and bases have distinct physical properties. Acids taste sour and feel sticky while bases taste bitter and feel slippery. Most of us also know that acids turn litmus paper red with a pH of 0-6.9 while bases turn litmus paper blue and have a pH of 7.1-14. But there are also many different definitions of acids and bases. In the Arrhenius definition of and acid and a base, acids produce hydrogen ions in a solution while bases produce hydroxide ions in a solution. In the Bronsted-Lowery definition acids donate a proton while bases accept a proton.
