Cuz the match can burn and turn in to ash so when it burn and turn in to ash you can't do nothing with the ash hop that make since
Hello!
An initial pH of 4,0 and an equivalence point at pH=9,1 corresponds to a titration curve for a weak acid to which strong base is added
An example would be the titration of Acetic Acid (CH₃COOH) with Sodium Hydroxide (NaOH)
CH₃COOH + NaOH → CH₃COONa + H₂O
The initial pH will be acid because only the Acetic Acid is present. In the equivalence point, there are no CH₃COOH nor NaOH present, and the only species responsible for pH is CH₃COONa. This is a weak base, as evidenced by the following reaction:
CH₃COO⁻ + H₂O ⇄ CH₃COOH + OH⁻
So, in the equivalence point, the pH will be basic. These observations help us conclude that this titration is of a weak acid with a strong base.
Have a nice day!
