Identify the weakest and strongest acids in the group below. The weakest acid is listed first in the responses. H₂Te, H₂S, H₂Se

Question

Quizplus · Accepted Answer

The strength of an acid is determined by its ability to donate a proton (H+ ion) in a solution. In this case, the anions are all made up of the same elements (S, Se, and Te) but with different numbers of sulfur and tellurium atoms. The anion with the Te atom (H₂Te) will be the weakest acid because Te is the least electronegative of these elements and will hold onto the proton more tightly. The anion with the S atom (H₂S) will be the strongest acid because S is the most electronegative of these elements and will release the proton most readily. Therefore, the correct answer is B as it has the correct order of acids from weakest (H₂Te) to strongest (H₂S).
