The Bronsted-Lowry definition of acids are that acids are compounds that give off H+ ions when you stick them in water. This definition also says that bases are compounds that can accept H+ ions when you stick them in water.
Properties of acids include the following:
* React with most metals to form hydrogen gas
* Taste sour (like lemons)
* Frequently feel "sticky"
* Usually gases or liquids
Properties of bases include:
* Feel "slippery". (FYI: The slippery feeling is caused because your skin dissolves a little when you touch them.)
* Taste bitter (like baking soda)
* React with oils and greases (that's why they're used as drain and window cleaners)
* Frequently solids (though ammonia is a gas that's usually dissolved in water)
pH values between 0 and 7 are acidic and pH values between 7 and 14 are basic. pH values of exactly seven are called "neutral" solutions - if the pH is 6.99 it's an acidic solution and if it's 7.01 it's basic.

An acid is a substance which when dissolved in water gives hydrogen ions as the only positively charged ions.
A base is a substance which when dissolved in water yeilds hydroxyl ions only.

what rishi said. but the bronsted-lowry falls short when it comes to acids with no hydrogen in it. acids give off protons (to become anions), bases accept protons (to become cations
furthermore, in a louis structure diagram, an acid is an electron pair acceptor, while a base is an electron pair donor

Acids donate Hydrogen ions, whereas bases accept Hydrogen ions.

when metals and non-metals react with air and water they form acid an bases.their difference can be detect by PH strips and litmus paper
