  An acid and a base are like chemical opposites. If a base is added to an acidic solution, the solution becomes less acidic and moves toward the middle of the pH scale. This is called neutralizing the acid.
C
 Baking soda contains sodium hydrogen carbonate(base) which neutralises the formic acid(acid) injected by bee sting.
