Hint: An acid is a molecule or ion capable of donating a proton, or, alternatively, capable of forming a covalent bond with an electron pair. And base is a substance which dissociates in aqueous solution to form hydroxide ions. These ions can react with hydrogen ions from the dissociation of acids to form water in an acid–base reaction.

Complete answer: Properties of acids:
-Aqueous solutions of acids are electrolytes, meaning that they conduct electrical current.
-Acids have a sour taste.
-Acids change the color of a certain acid-base.
-Acids react with active metals to yield hydrogen gas.
-Acids react with bases to produce a salt compound and water.
-Turn blue litmus paper red.
Properties of bases:
-Bases change the color of litmus from red to blue.
-They are bitter in taste.
- Bases lose their basicity when mixed with acids.
-Bases react with acids to form salt and water. ...
-They can conduct electricity.
-Bases feel slippery or soapy.
-Some bases are great conductors of electricity.

-Do not react with carbonates and turn red litmus paper blue.

Note:
Basic substances can be used as insoluble heterogeneous catalysts for chemical reactions. Some examples are metal oxides such as magnesium oxide, calcium oxide, and barium oxide as well as potassium fluoride on alumina and some zeolites. And acids are fundamental reagents in treating almost all processes in today's industry. Sulfuric acid, a diprotic acid, is the most widely used acid in industry, which is also the most-produced industrial chemical in the world.
