Consider the following unfinished table of weak acids with their corresponding pKa values and Ka values. Weak Acid pka 3.35 ка HNO2 HF HCN - 6.8*10-4 9.31 Arrange these three acids in order of increasing acid strength. (weakest) HCN <HF < HNO2 (strongest) n (weakest) HCN <HNO2 <HF (strongest) (weakest) HF <HNO2 <HCN (strongest) d (weakest) HNO2 <HCN <HF (strongest) Ce (weakest) HNO2 <HF <HCN (strongest)
The following reactions all have K>1. 1) HF (aq) + CN (aq) F (aq) + HCN (aq) 2) HNO2 (aq) + CN* (aq)_HCN (aq) + NO2 (aq) 3) HF (aq) + NO2 (aq)_F (aq) + HNO2 (aq) Arrange the substances based on their relative base strength. Clear All HCN strongest base CN intermediate base NO2 weakest base not a Bronsted-Lowry HNO2 base HF
Use the following acid ionization constants to identify the correct decreasing order of base strengths for the conjugate bases. HF: Ka = 7.2 ´ 10-4 HCN: Ka = 6.2 ´ 10-10 HNO2: Ka = 4.5 ´ 10-4 A. NO2- > F->CN- B. CN- > NO2- > F- C. F- > NO2- > CN- D. NO2- > CN- > F- E. F-> CN- > NO2- F. CN- > F->NO2 -
Which of the following is the strongest acid? CH3COOH, Kg = 1.8 x 10-5 HF, KA = 3.4 x 10-4 O HNO2, Kg = 4.6 x 10-4 HCN, KA = 4.9 ~ 10-10 HCIO, KA = 3.0 x 10-8
