Question

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

8 I Following Rens, ) MF(aq) + Cal(aq) + (aq) + Hen(aa). 2) HNO₂ (aq) + CN- (a) es MN (aq) + No (a) HFlag) + NOE (ages & Tag) + HNO2/ Ist on shows that He is stronger auld than HON, so it gives it to CNo to form HCN. 2nd Rxn prong that HNO is stronger auld than HON 3rd Rxn shows that HF is stronger and than HNO₂- 80' stronger acid is to then HNO, then HN. We know, STRONGER THE AUDI WEAKER THE CONJUGATE BASE F - Weakest base. Con Noe Intermediate base CNO a Strongest base III HF, HNO2, HEN s not a Bronsted-loway base .
