A student performs an experiment to determine the concetration of a solution of hypochlorous acid, hocl (ka = 3.5 x 10^-8) the student starts with 25.00 ml of the acid in a flask and titrates it against a standardized solution of sodium hydroxide with a concentration of 1.47 m the equivalence point is reached after the addition of 34.23 ml of naoh

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
