The most general idea of acids and bases is due to G. N. Lewis. A Lewis acid is a chemical species that can accept an electron pair, whereas a Lewis base is capable of donating an electron pair. The most commonly used (and useful) concept in soil and environmental ...Charles W. ...

Litmus or pH paper is filter paper that has been treated with a natural water-soluble dye so it can be used as a pH indicator, to test how much acid (acidity) or base (alkalinity) exists in a solution. You might have even used some to test whether the water in a swimming pool is...
What are Acids and Bases? Substances can be classified as acidic, basic, or neutral. The pH scale ranges from 0 to 14. The pH of an acid is below 7 and a base is above 7. Anything that has a pH of 7 is classified as neutral. Common household items such as vinegar and bleach ...
