Chemical reactions are defined as reactions which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical reaction.

There are several characteristics of chemical reactions like change in color, change in state , change in odor and change in composition . During chemical reaction there is also formation of precipitate an insoluble mass of substance or even evolution of gases.

There are three types of chemical reactions:

1) inorganic reactions

2)organic reactions

3) biochemical reactions

During chemical reactions atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

Answer:

The answer to your question is:  [H+]  = 0.0016

Explanation:

Data

pH = 2.8

process

                2.8 =  -log [H+]           then we get antilog

      antilog (-2.8 ) = [H+]    

      [H+]  = 0.0016
