Question

Bronsted-Lowry Acids and Bases: Predicting the qualitative acid-base properties of salts

No description necessary

**I only need the ranking of the pH**

Consider the following data on some weak acids and weak bases acid base name formula name formula hydrofluoric acidHF | 6.8 × 10-4 ammoniaNH NH3 11.8×10 -4 101 methylamine CH3NH2 methylamine CH3NH2 | 4.4 × 10 hydrocyanic acid HCN A49X 1O Use this data to rank the following solutions in order of increasing pH. In other words, select a'l'next to the solution that will have the lowest pH, a '2' next to the solution that will have the next lowest pH, and so on solution pH 0.1 MNH4Cl choose one 0.1 M CH3NH3Br choose one 0.1 M KCN choose one 0.1 M NaF V choose one 1 (lowest) Start Ove 2 4 (highest) Explain Next >>

Explanation / Answer

0.1 M NH4Cl< 0.1M CH3NH4Br<0.1HF<0.1MNaCN
