Which solution(s) are the most electrically conductive?

> Only formic acid is the most electrically conductive.

> Only chloric acid is the most electrically conductive.

> Only hydrobromic acid is the most electrically conductive.

> Both chloric and hydrobromic acid have the same electrical conductivity.

> All three solutions have the same electrical conductivity.

Which solution(s) are the most electrically conductive?

1. chloric acid (HClO3)

2. hydrobromic acid (HBr)

3. formic acid (HCOOH)

4. both chloric and hydrobromic acid

5. All three solutions have the same electrical conductivity

> Only hydrobromic acid is the most electrically conductive.

---> incorrect

> Both chloric and hydrobromic acid have the same electrical conductivity.

---> correct

These two acids are strong, so each will ionize to produce one proton and one anion in aqueous solution. As a result, they will have the same electrical conductivity.

※ 학생들에게 혼란만 주는 쓰레기 같은 문제.

A garbage problem that only confuses students.

HBr 산의 세기와 HClO3 산의 세기가 비슷하다고 생각할 듯...

( 참고 https://ywpop.tistory.com/4273 )

> 산의 세기가 비슷한 염산(HCl)과 황산(H2SO4)의 전기 전도도도 차이 난다.

산의 세기가 비슷한 HCl과 H2SO4의 전기 전도도도 차이 나는데,

어떻게 이 둘보다 산의 세기가 훨씬 더 차이 나는

HBr과 HClO3의 전기 전도도가 비슷하다고 설명하는가?
