A student has finished titrating KMnO_{4} (in buret) with oxalic acid of unknown concentration. The student notices small drops of KMnO_{4} on the neck of the flask. This means these drops were dispensed from the buret but did not react with the oxalic acid. How will this affect the calculated molarity of the oxalic acid

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.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
