Consider three generic acids: HX, HY, and HZ Rank these acids according to strength. Strongest acid HZ HY HX
HX HY HZ 2. Use the illustration of the three acids (HX, HY and HZ) above to answer the following questions: Which of the acids is a strong acid and why? i. а. HХ b. HY c. HZ Which of the acids will have the highest pH and why? а. HX b. HY ii c. HZ li. Which of the acids will have the smallest dissociation constant Ka? а. НХ b. HY c. HZ 2.
The following scenes represent three weak acids HX, HY, and HZ dissolved in water (H2O is not shown). Rank the order of the acids in order of increasing pk, HA= H30* HX ну HXHZ< HY HX < HY <HZ HY HZ< HX HZ< HY <HX HY <HX <HZ
Consider three generic acids with the relative stengths: HX > HY > HZ. Arrange their conjugate bases from strongest base to weakest base. Strongest base Weakest base Answer Bank Y- out us careers privacy policy terms of use contact us
